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!
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 ?
@@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.
That was amazing, thanks!
🙏
what a leacture short precise and accurate
well explained 👍👍
Thank you so much you were such a big help!
amazing video... amazing visuals...amazing content.. keep going.

Just seconds to your video, I have gotten what I need
Thanks
Got right on a similar question on my exam thank to you.
Saved my dissertation! Thank you so much for this astonding video!
YOU ARE AMAZING!!!!!
Thank you Mr Joshua, you sounds very humble and articulate professor wish i had a chance to be your student
🙏
Thanks professor for the wisdom
I got nothing from the three-hour class last week, but now I can understand everything in just 7 min. Thank you so much 😊
easy to understand. thank you so much ❤
Perfect! Thank you
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
the writing disturb when you are reading the table
V good

What do you mean by "pass the test?"
@@joshemman pass the test my professor use this term, which means the distribution is valid. Thanks for helping and clarifying my point.

You're right, the distribution is valid when the test statistic is smaller than the critical value.
The expected value is only 25% how does it become 35
Expected value can be expressed either as a proportion or a number of observations (frequency)
140×0.25 =35
