How would you justify using the chi-squared test? "Because the experiment...

... involves a potential relationship between different data sets"

How would you justify using the correlation test? "Because the experiment...

... involves an association between two sets of data"

Which statement is a suitable null hypothesis?

There is no correlation between chocolate consumption & age

Which statement is a suitable alternate hypothesis?

There is a difference in the effect of dark & milk chocs

How would you justify using the t-test? "Because the experiment...

... involves comparing the mean values of two sets of data"

Which statistical tests have we learned about this school year?

Correlation test, t-test, chi-squared test

p<0.05, so the difference is significant

and the null hypothesis should be rejected

7
Which statement is a suitable null hypothesis?
The results of the experiment don't show a clear effect

There is no correlation between chocolate consumption & age
Nothing happened in the chocolate age experiment
8
Which statement is a suitable alternate hypothesis?

p<0.05, so the difference is significant
and the results are true
and the null hypothesis should be rejected
and the null hypothesis should be accepted
and the results are false
