Jana is an action researcher who wants to better understand what predicts student success on the statewide standardized biology competency test. As her data sources, she administers the Biology Interest Survey (BIS) to all of her students. She categorizes students into two groups:

a. those who have taken biology before and those who have not, and she also administers an in-class exam.

b. The scores from the in class exam are then 'curved.' She uses these data sources as a means to predict student performance on the statewide biology competency exam.

Answer: I found the complete statement on google:

Jana is an action researcher who wants to better understand what predicts student success on the statewide standardized biology competency test. As her data sources, she administers the Biology Interest Survey (BIS) to all of her students, she categorizes students into two groups: those who have taken biology before and those who have not, and she also administers an in-class exam. The scores from the in-class exam are then 'curved'. She uses these data sources as a means to predict student performance on the statewide biology competency exam.

In Jana's study, the in-class biology exam is best described as:

a. an attitudinal measure.

b. a projective assessment.

c. an achievement test.

d. an aptitude test.

The correct answer is "c. an achievement test.".

This is because an achievement test allows us to know about who took biology before and who didn't, and their qualifications.
