Question

Calculate the mean, median, or mode of a distribution. The given data lists the number of minutes it took an individual to swim the length of the pool in 10 separate attempts: 2.8, 2.5, 2.6, 2.8, 2.5, 2.6, 2.6, 2.4, 2.5, 2.7. Select the option that shows the correct mean, median, and mode.

A) Mean: 2.5, Median: 2.6, Mode: 2.8
B) Mean: 2.6, Median: 2.55, Mode: 2.5
C) Mean: 2.6, Median: 2.6, Mode: 2.5 and 2.6
D) Mean: 2.6, Median: 2.6, Mode: 2.6

Answer 1

The mean, median, and mode of the given data set are 2.6, 2.6, and 2.5 and 2.6 respectively.

Step-by-step explanation:

The mean is the average of a set of numbers. To find the mean, add up all the numbers in the set and divide by the total number of values. For the given data, the mean is 2.6.

The median is the middle value in a set when the values are arranged in ascending order. To find the median, first arrange the data in ascending order. If there is an odd number of values, the median is the middle value. If there is an even number of values, the median is the average of the two middle values. For the given data, the median is 2.6.

The mode is the value that appears most frequently in a set. If there is no value that appears more than once, the data has no mode. For the given data, the mode is 2.5 and 2.6..
