Question

Imagine the Biology department needs to decide which lab curriculum yields better student outcomes. Five sections are assigned to curriculum A, and five sections are assigned to curriculum B. All sections are administered a pre- and post-test that measures students' attitudes toward science and knowledge of biology. The department wants to see if students' gains are greater in one curriculum or the other. What statistical test should be done to determine if there is a significant difference? Explain why you chose this test.

Answer 1

ANSWER:

• A mode ought to be computed.
• First compute the distinction between gains for every understudy in their pre-and post-test
• i.e. (gain in post - test ) - (gain in pre-test) for both educational programs.
• At that point compute the mode estimations of the distinctions and see which of the 2 educational modules has a higher mode esteem. That specific educational modules has higher additions.
• Mode is a test that computes the esteem which is most plentiful in a populace.
• To discover whether the computed mode esteems for the 2 educational programs is altogether unique play out an unpaired understudy t-test on it. An understudies t-test predicts whether 2 free factors are fundamentally not the same as each other or it occurred by possibility.
