you teach in an amazing way sir, my concept is solid clear now. Literally spent ages looking for a good stats video since ive never studied the subject before and found this gold. THANKYOU! keep going!
You are an excellent instructor. You will go very far! I have watched any videos about this topic and still. I would end the video with the same dumb level of understanding as when I began the video. But when I stumbled across this version of the video, I had no other choice but to understand "Sampling Methods". I understand clearly the entire ramification from every introductory level aspect. thankssssssssss
Check your understanding: Administrators at Jones Elementary School surveyed a random sample of 100 of their fourth graders to see how they felt about extending recess time from 20 minutes to 30 minutes. Identify the population and sample in this scenario. A. The population is all students at Jones Elementary School; the sample is the 100 fourth graders surveyed B. The population is all fourth graders at Jones Elementary School; the sample is the 100 fourth graders surveyed C. The population is all fourth graders at Jones Elementary School; the sample is all the students at Jones Elementary School D. The population is all students at Jones Elementary School; the sample is all of the fourth graders at Jones Elementary School
Giving the example of Stratosphere (i.e. layers) to explain stratified sampling was so cool! It made the missing connection in my understanding! Thanks!
well, after reading for 20 minutes, I nearly comprehended %50 of those terminologies. Alternatively, watching your video is a great time and energy saver. Well explained.
Thank you so much because I'm struggling. I hope your channel continues to grow because you're doing a brilliant job! New subscriber...looking forward to more content.
I've watched this video so many times! =/ I’m having difficulty with my homework! I want to know if I am doing this right. Any feedback would be highly appreciated. An airline company would like to know the number of pieces of carry-on luggage (on average) on each flight. However, instead of looking at every flight, the airline company decides to take a sample of flights. 1. Describe a simple random sample to create such a sample. Population (N)- entirely of something- All flights Sample (n) - part of the population- select based on features and characteristics- first class, economy, international and domestic flights. In order to take a simple random sample of a sample of flights, we can select based on criteria mentioned above and use a computer random generator to generate random numbers. 2. Describe a stratified random sampling technique to create such a sample. In a stratified random sampling- the population of flights would be divided into different subgroups of the population (strata). Stratas are homogenous to themselves. In this case, each characteristic can be its own strata (first class, economy, international and domestic flights). All passengers who fly economy, would be placed in one strata or subgroup. All passengers who fly first class would be placed in its own strata. All passengers who have domestic flight, would be placed in another strata. All passengers who have an international flight, would be placed into another strata. After each strata is formed, we can take a random selection sample of each strata to ensure that every specific subgroup was represented, thus we can make better inferences about the population.
Great Teacher. As a ADHD-Dude i gotta say, i had no concentration issues watching you! Greetings from Germany
Exactly, same here!!
Your teaching communicative skills are off the charts. Your simplification of a generally complex topic is refreshing. Thank you.
Thank you for the kind words :)
More cleared.... Simplified.,.. Excellent presentation.... No boring.... 👌🏻👌🏻🔥🔥 V. Good
So nice of you! Appreciate the message 🙏🏻

thank you for the kind words :)
This was a great explanation and I watched like four other videos before this. This was the best one as I am a visual learner
Great to hear!

Such kind words! Thank you so much 😊
Check your understanding:
Administrators at Jones Elementary School surveyed a random sample of 100 of their fourth graders to see how they felt about extending recess time from 20 minutes to 30 minutes.
Identify the population and sample in this scenario.
A. The population is all students at Jones Elementary School; the sample is the 100 fourth graders surveyed
B. The population is all fourth graders at Jones Elementary School; the sample is the 100 fourth graders surveyed
C. The population is all fourth graders at Jones Elementary School; the sample is all the students at Jones Elementary School
D. The population is all students at Jones Elementary School; the sample is all of the fourth graders at Jones Elementary School
I think (B)
B. The population is all fourth graders at Jones Elementary School; the sample is the 100 fourth graders surveyed
B

Thanks for subbing!
Wow I'm so glad I have found your channel! You explain very interesting and understandable ❤
Happy to help 🤓
Thank you, you're such a great teacher - this really helped with my research methods class for grad school!
You're very welcome!
love how you explain everything
Thank you for watching!
I wish you were my economic statistics tutor, I would not have had to do the course twice haha. Great video and the visuals are really helpful..
Happy I could help!
Thank you so much. I have a hard time with some of this type of math. You explained it well
Glad I could help!
really good - simply explained
This is incredibly helpful to me as I prepare for my Research Methods exams tomorrow
Best of luck!
That was very helpful, thank you so much.
You're very welcome!
you are a life saver
😇😇
Excellent examples and descriptions! Just what I was looking for!
Thanks for watching :)

This looks great!! I wouldn't change anything :)
Perfect!
Wow... very informative...
Glad it helped!
I really appreciate it
Thank you 🥰
You’re welcome 😊
This was really helpful thank you ❤
You're so welcome!
Excellent
Thanks
You're awesome
Do you have a video about cluster sampling?
Unfortunately no
Thanks a lot!
Nice video
good presentation , may you differentiate for me stratified and cluster probability
I found this link which may help clarify: keydifferences.com/difference-between-stratified-and-cluster-sampling.html
What is the stratum from this stratified
What is the difference between Stratified Sampling and Cluster Sampling?
Hi sir, plz upload vedios on theriotical and conceptual framework and analysis and interpretation of data.
Our exams are nearing.
What topics are you thinking about?
Which method of sampling can be used when conducting a research on bullying in a certain area?
Amazing
Thank you! Cheers!
Thank you sir, can you also recommend a good book for this topic?
