Gd mrng mam bahut achha samjhate h aap thank u soooo much but mam ek confs h ye kaise pta kre ki dono me sig. Diffrnt h ya nhi jaise ek group me 13 or dusre me 23 h to kaise pta kre ki enme diffirent h ya nhi plz mam clr kre plz
If we are comparing mean scores of two groups and our null hypothesis is " there will be no significant difference between two groups". And if mean score of group A is higher than mean score of group B. Than before testing null hypothesis we can assume that if our null hypothesis be rejected than we can say that group A is higher than we have to subtract mean B from mean A and we also know that t score will come positive value.
One more thing null hypotheses is a nondirectional hypothesis it just tells about that difference is exist or not. It does not tell about the direction.
Mam null hypothesis one tailed and 2 tailed both hota hai... Hum null hypothesis me mat kehta hai ki M1 is greater or less then M2.. Hum kehtay hai there is no difference between two
again good question null hypothesis m ham NO, Not ko use karte hn .... Mean of experimental group is not lesser than or equals to control group.... it is the example of one tailed null hypothesis. i hope it will be helpful to u.
@@MetaEducationByShaliniMam yes both can be one tailed and two. But in most of the practical situations null hypothesis considered as the simple hypothesis and alternative as a composite hypothesis.
Which of the following is an one tailed alternative hypothesis: a) alternative hypothesis is population mean less than 0 b) null hypothesis is population mean is equal to 0 c) Alternative hypothesis is population mean is not equal to 0 d)both a and c
@@MetaEducationByShaliniMam I also think that a is correct because in c) case it is no equal sign in alternative then in null hypothesis there must be equal sign and it means the rejection region will be on both side of normal distribution and it will be two tailed test..
NPC pr koi bhi scores show kar sakte hn jese T scores ko bhi hamne show karke batya.... app kisi bhi test k raw scores ko bhi show kar sakte hn..... but un sabhi ki jo scaling hogi bo Z scores k according and equvalent hi honi chaiye,.... jese hammne T score k Mean 50 ko Z scores k Mean 0 k equivelent rakhne k baad m show kiya h .....app isko samjhne k liye lecture 12 ko ek baar fir dekh sakte hn to sayad apko clear ho....
Good question Anju The critical region of the sampling distribution of a statistic is also known as the α region. It is the area, or areas, of the sampling distribution of a statistic that will lead to the rejection of the hypothesis tested when that hypothesis is true. Means wo region jnha true hypotheses ke reject hone ke chances hote hn
mam first time statistics smj aaya h but kuch confusion h mam null hypothesis m 5%significant level pr two tailed test m aapne 1.96 and one tailed test m 1.65 kaise calculate kiya please reply mam
Because in one tail test the whole 5 % cases sift towards left or right side according to hypothesis.... And according to percentage of cases and covered area the 5% cases lie below the -1.645 and in case of positive one tail test 5%cases lie above +1.645 And and 1.96 is the value in twotail test
Mam aap boht bdyia smjya h.mam you clear my all doubts.mam u r great teacher.mam agr aap roj ek net k di bi kra de sirf previous papr kra de to mam vo bi smj ajye .aap sbhi doubt clear krdty ho

When we given a question to test hypothesis how we understand it is either one tailed or two tailed can you explain it in a simple example?

How to find the significance level value without using table
Nice super video
Thanks a lot
Gd mrng mam bahut achha samjhate h aap thank u soooo much but mam ek confs h ye kaise pta kre ki dono me sig. Diffrnt h ya nhi jaise ek group me 13 or dusre me 23 h to kaise pta kre ki enme diffirent h ya nhi plz mam clr kre plz
Two tail me sample size more than 30 hona jruri hai kya
no connection of two tail with size of sample.
Reframe the question and ask again.
iz the direction of differance known in advance in using 2 tailed test
Yes
Meta Education how mam
If we are comparing mean scores of two groups and our null hypothesis is " there will be no significant difference between two groups".
And if mean score of group A is higher than mean score of group B. Than before testing null hypothesis we can assume that if our null hypothesis be rejected than we can say that group A is higher than we have to subtract mean B from mean A and we also know that t score will come positive value.
One more thing null hypotheses is a nondirectional hypothesis it just tells about that difference is exist or not.
It does not tell about the direction.
Mam null hypothesis one tailed and 2 tailed both hota hai...
Hum null hypothesis me mat kehta hai ki M1 is greater or less then M2..
Hum kehtay hai there is no difference between two
again good question
null hypothesis m ham NO, Not ko use karte hn ....
Mean of experimental group is not lesser than or equals to control group....
it is the example of one tailed null hypothesis.
i hope it will be helpful to u.

Thanks,,,,, mam
Not only helpful but fruitful also
@@MetaEducationByShaliniMam is rejection area =level of significance?
Thanks maim
We will decide one-tailed or two-tailed on the basis of the alternative hypothesis, not on the basis of null hypothesis.
both can be one tailed and two tailed, and called as directional hypothesis, either directional null hypothesis or directional alternative hypothesis.
@@MetaEducationByShaliniMam yes both can be one tailed and two. But in most of the practical situations null hypothesis considered as the simple hypothesis and alternative as a composite hypothesis.
Mam please ye bataiye ki real jindagi me kis chiz me use karte hai
When we do research of something...we use hypothesis before the research and these are the tentative ideas that will be apply to actual research.
Yes
Di ham level of significance max time 5% ya 1% per kyu cheak krte hain ....
These are pre discussed level in statistics. meaning of these are 99% surety and 95% surety or confidence.
@@MetaEducationByShaliniMam thanks di 🙏
Nice video
Mam ist u are saying 5% = 1.96 or -1. 96...then u r saying 1.65 .. Confused plz clear
Which of the following is an one tailed alternative hypothesis:
a) alternative hypothesis is population mean less than 0
b) null hypothesis is population mean is equal to 0
c) Alternative hypothesis is population mean is not equal to 0
d)both a and c
Thanks for asking this question...
According to my knowledge option a should be correct.
@@MetaEducationByShaliniMam I also think that a is correct because in c) case it is no equal sign in alternative then in null hypothesis there must be equal sign and it means the rejection region will be on both side of normal distribution and it will be two tailed test..
Yes u r right
Thank u
Thanks for comment Abida.
👍🏻👍🏻👍🏻👍🏻
Mam 1% pr bhi hypothesis reject ho jati h wo bhi bta dijiye

In the question how find this is one tailed test or two tailed test????
when hypothesis is directional that means one tailed test
when it is non directional that means two tailed test
Good Diffrence off Sten and Stenine please🙏🏿
Already avilable
Thank u ❤️
You’re welcome 😊
Ma'am please cover the tests
ANOVA,Mann Whitney,spermans rank correlation
Ok will try
Very nice lecture mam...bt kya 1%case me bhi one tail & two tail test hota hai??
Yes we can use 1 tail and two tail test for any level of significan
Thanks mam
Thanks for comment Keshab.
Outstanding madam, I have to discuss with you please guide me
thanks parul..... pls tell what do u want to discuss with me.
Mam agar question me level of significance ya confidence level nahi btaya hai to kese solve krein?
Pls send me that question I will try to give u answer 👍
Mam critical region kya hota h
Good question Anju
The critical region of the sampling distribution of a statistic is also known as the α region. It is the area, or areas, of the sampling distribution of a statistic that will lead to the rejection of the hypothesis tested when that hypothesis is true.
Means wo region jnha true hypotheses ke reject hone ke chances hote hn
Mam how to find one tailed test and two tailed test in question
Agar no difference Diya h to two tail
Agar more than or less than h to one tail
@@MetaEducationByShaliniMam can u explain it properly I can't understand ...this topic is very much confusing me ...please help me
Why do you write in english when you do not speak in english?
mam first time statistics smj aaya h but kuch confusion h mam null hypothesis m 5%significant level pr two tailed test m aapne 1.96 and one tailed test m 1.65 kaise calculate kiya please reply mam
These are tabulated value
Mujhe samajh tu aa gaya pr ye real me kaha use karte hai ye smjh nahi aaya
what is logic behind getting "1.96" for 5% significance in two tailed
This all comes from NPC ... U should watch all videos related to NPC avilable on our channel... It will help u to get more clearity.😊 all the best
This came from z table
Take a problem as an example with x,m and solve using one tailed and two tailed
Mam my doubt is y u take 1.645 at 5% level of significance in one tail test , because its 1.96 na
Because in one tail test the whole 5 % cases sift towards left or right side according to hypothesis.... And according to percentage of cases and covered area the 5% cases lie below the -1.645 and in case of positive one tail test 5%cases lie above +1.645
And and 1.96 is the value in twotail test
I hope it will help u if u have futlrther any doubt than feel free to ask
Thanku mam
, t - test, F - test (one - way and ANOVA) ...... In pe kub tak lecture possible hoga mam
t test ... very soon..... but others pr abhi time lagega....
😅pichli saal ache se pda tha same question test me 0 mila mene toh use likha tha
Ye 1.96 table say kaisay daikhtay hain
