To find: Mean, median, and mode to the nearest tenth fir the set of data.
Answer to Problem 51S
Mean of the data is approximately 26.4, median of the data is 26.5 and mode of the data is 25.
Explanation of Solution
Given information:
The given set of data is 25, 28, 21, 26, 25, 27, 29, 30.
Calculation:
Arrange the data from least to greatest:
21, 25, 25, 26, 27, 28, 29, 30.
Since, mean is defined as the sum of the data divided by total number of data in a data set. Therefore,
Also, median of the data is middle number of the ordered data or the mean of the middle two numbers. Therefore,
And, mode of the data defined as the data that occurs most often. Therefore,
Hence,
Mean of the data is approximately 26.4, median of the data is 26.5 and mode of the data is 25.
