Descriptive statistics play an important role in analyzing data. It numerically summarizes key characteristics of variables. Measures of central tendency (mean, median, and mode) and dispersion (variance, standard deviation, and range) characterize the probability distribution. A histogram visualizes the distribution of numerical data, indicating the number of data points that lie within a range of values. For this assignment, you will perform descriptive statistics and create a histogram for selected variables in a dataset.

The dataset contains the following variables:
Nursing home administration has the objectives of higher utilization, higher patient satisfaction, and lower readmissions, and they need to make a decision on whether to retain the department manager based on average performance over the past 70 months.
For this assignment, create a descriptive statistics table and histogram based on the Assignment 1 Dataset. Write a narrative summary in a Word document and insert the table and histogram graphic into this document. See the “Copy From Excel to Another Office Program” resource for instructions. Submit both the Word document and the Excel file that shows the descriptive statistics output.
