Question

find the range and mean for the following data set.
23, 24, 25, 26, 27
range
mean

Explanation:

Step1: Calculate the range

The range is the difference between the maximum and minimum values in the data set.
Maximum value = 27, Minimum value = 23
Range = Maximum - Minimum = \( 27 - 23 = 4 \)

Step2: Calculate the mean

The mean is the sum of all values divided by the number of values.
Sum of values = \( 23 + 24 + 25 + 26 + 27 \)
First, calculate the sum: \( 23+24 = 47 \), \( 47+25 = 72 \), \( 72+26 = 98 \), \( 98+27 = 125 \)
Number of values = 5
Mean = \( \frac{125}{5} = 25 \)

Answer:

range: 4, mean: 25
