I got nothing from the three-hour class last week, but now I can understand everything in just 7 min. Thank you so much 😊

[@johnebbers5170]

Exact same for me, some bozo in the front row asked questions all class and the prof didn't stop him. I was like 200 other students were watching a private tutoring session.

YOU ARE AMAZING!!!!!

Thank u but how do we get the expected values?

[@joshemman]

For Expected Values, start at 2:21 kzbin.info/www/bejne/r2OXoml4nbecesU

[@princeisabel8594]

I pray I get an answer when it comes to rounding up .0584 doesn't sum to 1.6315 so why did we also pick that

[@kiki_bert]

the writing disturb when you are reading the table

[@loislovescheese4776]

what if you had 3 replicates for each variable (say i have variables a, b, c, d and 3 replicate values for each (eg variable a has values 0.1, 0.2, 0.3) can I do the chi squared test on the 4 variables? Do I have to find the mean of each variable then do the chi squared test? or is there a better test for that? Thanks!

[@kowtharhassan882]

Categorical data have no means

[@jahansaid6382]

Rejection region is bigger than 7.815 but the value we got is 1.6315 which is smaller than the rejection region, therefore the distribution should be Valid and it should pass the test? I don't why you said it doesn't pass the test ?

[@joshemman]

What do you mean by "pass the test?"

[@jahansaid6382]

@@joshemman pass the test my professor use this term, which means the distribution is valid. Thanks for helping and clarifying my point.

[@joshemman]

@@jahansaid6382 Since the distribution is stated in Ho, failing to reject Ho means it is valid. You're right, the distribution is valid when the test statistic is smaller than the critical value.

V good

[@andr3wtk]

I wish were my teacher!

[@joshemman]

[@DucusinAlexisP]

The expected value is only 25% how does it become 35

[@joshemman]

Expected value can be expressed either as a proportion or a number of observations (frequency)

[@Growup066]

140×0.25 =35
