0:00 Mean = Sum/N, The Total of The Numbers Added up/How many numbers you are working with. 1:47 Median = Middle Number. 2:20 Mode = The Most Frequent number to appear in the set of numbers. 6:40 Range = Highest/Maximum Number subtracted by the Lowest/Minimum Number. 7:45 Quartiles = 25%, 50%, 75%, 100%; the 4 quarters.
🎯 Key Takeaways for quick navigation: 00:43 📊 *Mean is calculated by summing the numbers and dividing by the count. In this example, mean is approximately 15.43.* 01:52 📏 *Median is the middle number of a dataset. Eliminate the first and last numbers, then move towards the middle. In this case, median is 14.* 02:32 📊 *Mode is the most frequently occurring number. In this case, mode is 7 as it appears twice.* 02:50 📏 *Range is the difference between the highest and lowest numbers. In this example, range is 25 (32 - 7).* 04:13 📊 *For a new dataset, mean is calculated similarly. In this case, mean is 32.25.* 05:34 📏 *When finding the median for an even dataset, average the two middle numbers. Here, median is 29 for the second dataset.* 06:22 📊 *In a bimodal dataset, there are two modes. Example: 15 and 59 are both modes.* 08:44 📏 *Quartiles (Q1, Q2, Q3) split a dataset into four parts. Q2 is the median, while Q1 and Q3 are medians of the lower and upper halves.* 09:29 📊 *Interquartile range (IQR) is the difference between Q3 and Q1. Useful for identifying outliers.* 14:54 📏 *Identify outliers by checking if a number is outside the range (Q1 - 1.5 * IQR to Q3 + 1.5 * IQR).* 19:32 📏 *Construct a box and whisker plot using Q1, Q2, Q3, minimum, maximum, and outliers if any.* 22:26 📊 *Determine if a point is an outlier based on its position relative to Q1, Q3, and 1.5 times the IQR.* 26:54 📏 *Skewness to the right (positive skew) has a longer tail on the right. Mean is greater than median.* 30:04 📏 *Skewness to the left (negative skew) has a longer tail on the left. Mean is less than median.* 31:40 📊 *Dot plots visually represent the distribution of data points in a dataset.* 32:23 📊 *To construct a dot plot, create a number line and place dots above corresponding numbers in the dataset.* 33:29 📈 *The mode in a dot plot is the number with the most dots; in this case, the mode is 3.* 34:18 🌱 *To make a stem-and-leaf plot, organize the data with stems (left) and leaves (right), representing each number.* 38:51 📊 *A frequency table shows the occurrence of each number in a dataset.* 41:49 🧮 *Calculate the mean using a frequency table by summing (value * frequency) and dividing by the total number of data points.* 42:20 📊 *Histograms visualize data distribution, with connected bars; different from bar graphs.* 45:55 📊 *Create a histogram by categorizing data into classes and representing frequencies in each class with connected bars.* 50:52 📊 *A cumulative relative frequency table helps find percentiles; 60th percentile is the average of 5 and 6 (5.5).* 52:14 📊 *To find the 80th percentile, average the values where the cumulative relative frequency crosses 0.80 (7.5).* 52:43 📊 *If a percentile falls between two values, average those two values to determine the corresponding data point.* Made with HARPA AI
shouldn't the median be 23? they asked for the median of the data set, he basically rearranged the data set, making his own data set but the question asked for the original data set
By only watching the intro once, I could replicate this the whole thing on my own. Considering I am an average dude, I find it amazing, and the only explanation -you are a remarkable teacher.
New Subscriber from Philippines. Statistic subject is what I got in my college days during 2005-2010. Now, I need to recall them for MBA course. Thanks for creating this channel.
I'm 28, I love Math but I never understood it during my school days which made me believe I'm not really good at Math and not smart enough for it. But I'm giving it a try again at my age, I want to be good at it, thanks for your videos!
The entire interent is a big giant library, don't forget to add your learnings to the internet back so that others can benefit from it just the way you did
So glad I subscribed to the membership. This cleared up a lot of confusion. I have 3 weeks left of my stats class, and I really need to make sure I pass.

Hey, just wanted to give you my feedback, i've been revising for my stats exam using your videos, and they've helped since i was really poor at the subject, sat for the exam today,and i hope i'll pass. Just wanted to say thank you
Determining the outliers through this interval which is a function of the IQR makes all senses, but the choice of the factor 1.5(IQR) as the tolerance range beyond Q1 and Q3 needs some logical justification. The underlying concept is though clear, which is setting the borderline within the distribution beyond which any score from the data set is to be characterized as an outlier. Thanks for great work and concise steps!
I watched this entire hour video and it was completely worth it! My instructor is making it sound harder than it is lol THANK YOU THANK YOU THANK YOU!!!❤

PRAISING THE LORD- that I have come across your page - I am currently in college being that I have not been in school since 2012. anywho I'm currently taking a statistics class and this help to inform me on what exactly I'm walking into .
Thankyou so much . Because you taught Statistics so well. I am thinking of taking Stats as a main subject in my career . I am aspiring data scientists . And i have recently completed my graduation . I want to thankyou for teaching me so well .
Covers multiple topics? Check. Somehow relates one topic to another? Check. Timestamps? Check. Simple explanations? Check. How to use the information? Check. You've got to be kidding me. Even though I watched the whole video while also writing them in my notebook, and I also liked, and subscribed, this person deserves a grand award for the quality of this vid tbh. Thank you so much. Seriously.
for my intro stats class i dont have to know HOW to make the graphs, but understanding how they're made and what they show us compared to each other really helps. better than my math teacher fr
Wonderfully done lesson. I clicked for a general refresher, which this does well. But I wish I had this video when I originally started my stats class in high school. My teacher was TERRIBLE, both at teaching AND at statistics. Two other students and I were constantly correcting her on rather basic mistakes. Halfway through the school year, she left for a month because she was taking an intro to statistics crash course 😑...she had no business teaching an AP Stats class. But the AP calculus teacher was already spread to thin to do it. He taught pre-cal calculus and intro to number theory so he couldn't. He was the best teacher I ever had. If I had these quality videos back then, I wouldn't have grown to have a grudge against statistics. Luckily, I had an amazing professor in college who fixed that. But my intro to it was rocky at best. Keep up the great work dude!!!
I’m trying to decide which math class to take at my community college and I won’t lie, I’m trying to pick the easiest college level class (I only need one math class my major) so I think watching your video may give me an idea on whether or not I’ll like intro to statistics.
Sir thank you! thank you for taking the time to make these videos. Im addicted to them! I have a teacher who is very good at his job but because math is not my cup of tea I do not do well on keeping up with his way of teaching, but you keep things so simple and clear and I just understand it better after watching your videos! As well as I love your voice :) Thank you once again

I took statistics in college. I think for anyone who doesn’t have the money this is good, but you could simplify it. Also, it’s good to have cartoons 👍 Remember, even with an hour, you have to try and keep it interesting. Statistics is all about what you are analyzing, and I think it might be better to first come up with the situation or the issue, and then break it down after you have an overview
sir your teaching is excellent, method is very easy to understand, i request please add examples, why people need mean in their daily lives, why and where. along with that in writting research papers where it can be used, and how to interpret the statistics data and results. thank you.
You are amazing… your videos are the greatest source of knowledge…it will be really good if you can give bit theoretical knowledge before solving questions,,,like what is basic difference between bar graph and histogram etc But honestly …thank you from core of my heart
🎯 Key Takeaways for quick navigation: 00:02 Arrange *data in ascending order. Calculate mean by summing and dividing by the number of data points. Mean for dataset (7, 7, 10, 14, 15, 23, 32) is approximately 15.43. Median is the middle number, so eliminate first and last, then middle two, resulting in median 14. Mode is the most frequent number; here, 7 is the mode. Range is the difference between the highest and lowest numbers, so it's 32 - 7 = 25.* 03:19 Similar *problem with eight numbers (11, 15, 21, 37, 41, 59), calculating mean (32.25), median (29 as there are two middle numbers), mode (15 and 59, bimodal), and range (59 - 11 = 48).* 07:05 Introduction *to quartiles (Q1, Q2, Q3) and interquartile range (IQR). Q2 is the median, Q1 is the median of the lower half, Q3 is the median of the upper half. IQR is the difference between Q3 and Q1. Outliers are identified if outside the range of Q1 - 1.5*IQR to Q3 + 1.5*IQR.* 10:25 Example: *Identifying Q1, Q2, Q3, calculating IQR, and checking for outliers (27 is not an outlier). Construction of a box and whisker plot using the obtained values.* 17:47 Another *example data set (13, 16, 18, 22, 23, 25, 28, 29, 31, 38, 50). Calculating Q1, Q2, Q3, IQR, identifying the outlier (50), and constructing a box and whisker plot.* 26:22 Explanation *of skewness in data distribution. A symmetrical distribution has mean = median; skew to the right means mean > median; skew to the left means mean < median. Visualization of skewness using box plots.* 31:53 Dot *plot creation for data set (5, 8, 3, 7, 1, 5, 3, 2, 3, 8, 5). Mode is the number with the most dots, so mode is 3.* 33:59 Introduction *to stem and leaf plots. Example data set (4, 9, 13, 13, 17, 21, 36, 38, 38, 56) demonstrated in stem and leaf plot form.* 34:32 Stem-and-leaf *plots involve organizing data into stems and leaves, helping visualize distribution.* 38:36 Frequency *tables are used to organize data and display the frequency of each value, aiding in understanding data distribution.* 42:04 Histograms *visually represent the distribution of a data set, with bars connected to show the relationship between values.* 47:26 Creating *a table with frequency, relative frequency, and cumulative relative frequency provides a comprehensive view of data distribution.* 51:23 Percentiles *can be determined using cumulative relative frequency tables, aiding in understanding data distribution and identifying specific percentiles.* Made with HARPA AI

07:05 Introduction *to quartiles (Q1, Q2, Q3) and interquartile range (IQR). Q2 is the median, Q1 is the median of the lower half, Q3 is the median of the upper half. IQR is the difference between Q3 and Q1. Outliers are identified if outside the range of Q1 - 1.5*IQR to Q3 + 1.5*IQR.*
10:25 Example: *Identifying Q1, Q2, Q3, calculating IQR, and checking for outliers (27 is not an outlier). Construction of a box and whisker plot using the obtained values.*
17:47 Another *example data set (13, 16, 18, 22, 23, 25, 28, 29, 31, 38, 50). Calculating Q1, Q2, Q3, IQR, identifying the outlier (50), and constructing a box and whisker plot.*
26:22 Explanation *of skewness in data distribution. A symmetrical distribution has mean = median; skew to the right means mean > median; skew to the left means mean < median. Visualization of skewness using box plots.*
31:53 Dot *plot creation for data set (5, 8, 3, 7, 1, 5, 3, 2, 3, 8, 5). Mode is the number with the most dots, so mode is 3.*
33:59 Introduction *to stem and leaf plots. Example data set (4, 9, 13, 13, 17, 21, 36, 38, 38, 56) demonstrated in stem and leaf plot form.*
34:32 Stem-and-leaf *plots involve organizing data into stems and leaves, helping visualize distribution.*
38:36 Frequency *tables are used to organize data and display the frequency of each value, aiding in understanding data distribution.*
42:04 Histograms *visually represent the distribution of a data set, with bars connected to show the relationship between values.*
47:26 Creating *a table with frequency, relative frequency, and cumulative relative frequency provides a comprehensive view of data distribution.*
51:23 Percentiles *can be determined using cumulative relative frequency tables, aiding in understanding data distribution and identifying specific percentiles.*
