Given the following data set: 5, 7, 12, 15, 18, 20, 25. Find the minimum, the average and use descriptive statistics to describe the data set.
Answer
Step 3: Finally, let's use descriptive statistics to describe the data set. Descriptive statistics provide simple summaries about the sample and the measures. These summaries may either form part of a descriptive statistics analysis, or they may be woven together with 'measure of spread' to form a more powerful statistical analysis.
Step 1 ：Step 1: First, let's find the minimum. The minimum is the smallest number in the data set. By looking at the data set, we can see that the smallest number is \(5\).
Step 2 ：Step 2: Next, let's find the average. The average is found by adding all the numbers in the data set and then dividing by the number of values in the set. So, \((5+7+12+15+18+20+25) \div 7 = 14.57\)
Step 3 ：Step 3: Finally, let's use descriptive statistics to describe the data set. Descriptive statistics provide simple summaries about the sample and the measures. These summaries may either form part of a descriptive statistics analysis, or they may be woven together with 'measure of spread' to form a more powerful statistical analysis.
