Provide a table in which you summarise complete descriptive statistics on 'salary' and 'age range' (including but NOT limited to measures of central location, measures of variability, etc.). Then use the information in the summary table that you have prepared to calculate the coefficient of variation for 'salary' and 'age range' across three campus locations. What insights could you potentially gain from these results?2- Develop contingency tables (use percentages) to provide joint information on:a) Employment type and salaryb) Age and salaryc) Gender distribution and type of employment for each of the three campuses.Note: Carefully explain your tables.3- Graphically demonstrate the output of questions 1 and 2.4- Prepare a set of bar charts to graphically represent the frequency distribution of the following categories for each of three campuses (CNS, TSV, and SG) separately. Categories are: job role, education, country of residence.5- Prepare a set of pie charts to graphically represent the percentages of following variables: gender, location and education.
