A researcher wants to test whether marks for undergraduate statistics units are influenced by how much time the students spend in studying statistics units during the semester. The researcher also wants to compare the results across gender and age groups. For this purpose, the researcher plans to survey a sample of undergraduate level students who studied statistics last semester. Using a maximum of 200 words for each part (Parts 1 to 4), answer the following questions. Suppose the researcher collected data from 110 respondents. For each respondent, the number of hours spent on studying statistics during 2 weeks period and the marks were recorded. The data are stored in the file Assignment Dataset.XLS sheet available in the Written Assignment folder. Using this data and EXCEL, answer the questions below. Part 4 (200 words) [4 Marks] The researcher wishes to investigate the association between the number of hours spent on studying statistics and the marks a. Explain what could be the independent variable (X) and the dependent variable (Y). b. Using Excel, compute a numerical measure that measures the strength of the linear relationship between the marks and study time. Interpret this value.
