Question
Problem statement: Kuya conducted a study to compare selenium levels between beef, chicken, turkey and lamb. He collected 100-mg samples of raw meat for each one. Is there a significant difference in selenium levels?
The appropriate test for this problem is:
t test for one sample
t test for dependent samples
t test for independent samples
one-way ANOVA
repeated measurements ANOVA
correlation analysis
linear regression
multiple regression
one-variable chi-square
two-variables chi-square
Problem statement: Kuya created a multiple choice test with 100 items. He wanted to check if the answer options are randomly distributed throughout the test so that there should be equal proportions of (a), (b), (c), and (d) as correct answers. He compared the actual frequencies of correct answers to the expected equal proportions. Are his correct answers equally distributed?

Explanation / Answer
For the First Problem : We used the One Way ANOVA to compare the the significant difference of the mean amount of selenium levels between beef, chicken, turkey and lamb.
To Compare the significant difference between the multiple means we used ANOVA.
For the Second Problem : We used one-variable chi-square test to check whether the data is randomly distributed or not.
