Assignment 2: Using Descriptive Statistics
In the news, we are constantly bombarded by statistics such as unemployment rates, stock market swings, or changes in the housing market. A vast majority of the statistical information presented to us is in the form of descriptive statistics. In descriptive statistics, a sample is taken, and values such as mean, median, mode, standard deviation, and variance are determined. These values are used to compare to other samples or are used as a measure of the current state of a population. The use of descriptive statistics is a common practice in the decision-making process in many professional fields.
In this assignment, you will use descriptive statistics to make an informed decision—in this case, to decide whether you are going to purchase a new car. Consider the following scenario:
