Question

Think of a problem dealing with two variables (Y and X) that you may be interested in. Share your problem and discuss why a regression analysis could be appropriate for this problem. Specifically, what statistical questions are you asking? You should describe the data collection process that you are proposing but you do not need to collect any data.

Answer 1

(1)

Problem dealing with two variables X and Y:

Study on the relationship between

X =Number of hours spent daily on studies

and

Y = Marks in the examination.

(2) A regression analysis could be appropriate for this problem because though it is well known that there is a direct correlation between hours of study and marks in the examination, proper statistical procedure can be applied on regression analysis so that person can predict his marks based on his study. Further the research can also help a student to determine how many more hours he should study in order to get marks higher than he obtained last time.

(3) The data collection procedure:

Log book is to be maintained on hours of study per day. Marks obtained on various examinations conducted are to be recorded.

(4) Caution:

Any confounding variable in this study should avoided. During the entire period of the research study, time should not be wasted on computer games, movies, unnecessary wastage of time with friends etc. which are the possible confounding variables in this research activity should be avoided.
