Organizing and presenting data 0 Use the lter tool in Excel to separate the Salary variable into two groups: one for Females and the other for Males. 0 First, designate two separate columns aside from your data set, one for Female Salaries and the other for Male Salaries; write the titles. Now lter (this tool is under Data tab) the gender variable to see only female values; then copy the corresponding female salary values and paste it to the Females Salaries column created. Repeat the previous steps to copy and paste the salaries for males into the Male Salaries column made. 0 Organize and analyze the data for each group O Organize the values of the Female Salaries into ve classes. To do so, you need to nd the class interval (CI) using the formula CI : (max value min value)f5, and round it to the greatest whole number, i.e. 12.309 :13. . Your rst class will start from the minimum value of the salary minimum, and the endpoint will be (minimum + CI). Example: start at 30000, end at 30000 + 12560 : 42560
