a)Cross-sectional
b)Longitudinal
c)Cross-sequential
d)double-blind

Answer 1

Your answer is B (Longitudinal)

Longitudinal studies can last anywhere from weeks to decades, although they tend to be at least a year long.

What is an example of a longitudinal study? The 1970 British Cohort Study, which has collected data on the lives of 17,000 Brits since their births in 1970, is one well-known example of a longitudinal study.

In a longitudinal study, researchers repeatedly examine the same individuals to detect any changes that might occur over a period of time. Longitudinal studies are a type of correlational research in which researchers observe and collect data on a number of variables without trying to influence those variables.

Answer 2

Longitudinal

Option B.

Step-by-step explanation:

Longitudinal type of research design is a type of research design which takes in to consideration the same group for the study but this study goes on for a long period of time.

This type of research design is longitudinal in the sense that the research has same group of students in it but the study will go on for many years to see the effect of the new method for learning math for different years of life of those students.
