Mean, Median, Mode, and Range

What is the mean, median, mode, and range of the following numbers: 150, 95, 210, 45, and 55?

a. Mean: 111; Median: 95; Mode: None; Range: 165

Answer:

The mean of the numbers 150, 95, 210, 45, and 55 is 111. The median is 95. There is no mode in this set of numbers. The range is 165.

To calculate the mean, you add up all the numbers and then divide by the total number of values. In this case, (150 + 95 + 210 + 45 + 55) / 5 = 111. To find the median, you arrange the numbers in order from smallest to largest and find the middle number. In this case, the numbers in order are 45, 55, 95, 150, and 210. The middle number is 95. The mode is the number that appears most frequently in a set of numbers. Since none of the numbers repeat in this case, there is no mode. The range is the difference between the largest and smallest numbers in a set. Here, the largest number is 210 and the smallest is 45. So, 210 - 45 = 165.
