A researcher who studies mental health is interested in the length of time (in days) that a patient stays in the hospital after they have presented to emergency having suicidal ideation. The researcher follows the first 30 patients during the month of January and follows them until each one of them is released. Below is the histogram of the data obtained from the 30 patients. 1. What is the shape of this distribution and please construct a frequency table. Given the shape and type of data, which measure of central tendency would you be more likely to report? Why?

In a frequency distribution graph, frequencies are presented on the and the scores (categories) are listed on the 1 Question 13 options: X axis; Y axis horizontal line; vertical line Y axis; X axis class interval; horizontal line

A large company's human resources manager undertakes a research that examines the employment records of 500 employees for absenteeism over the previous year. The data is organised into a frequency distribution by the business researcher conducting the study to assist the human resources manager in analysing the data. This graphs show the frequency distribution. Class interval Frequency 0 – 1 218 2 – 3 207 4 – 5 56 6 – 7 11 8 – 9 8 List three specific uses of cumulative frequencies in business. Display a relative frequency histogram and relative frequency polygon for these data. Find mean, median, mode, variance and standard deviation for grouped data.
