The ages, in years, of randomly selected employees are 34, 41, 28, 35, 27, 44, 29, 33, 41, and 39.
*To solve for measures of center, we first need to reorder the numbers on paper from LEAST to GREATEST.
*Count the values in the problem to make sure you have the same number of values on your ordered list.
1)To find the RANGE, we will subtract the highest value - the lowest value.
Range =
44 - 27 = 17
2)To find the MEAN (average), we add up all the values and divide by the total number of values.
( 27 + 28 + 29 + 33 + 34 + 35 + 39 + 41 + 41 + 44 ) / 10 = 34.1
Mean = 34.1
3)To find the MEDIAN (middle value), we find the middle value in our ordered list. Since there are 10 values, the median will be the average of the 5th and 6th values.
Median = ( 33 + 34 ) / 2 = 33.5
Therefore,
Range = 17
Mean = 34.1
Median = 33.5
what is the mode
The mode is the value that appears most frequently in the data set.
In the given data set of ages: 34, 41, 28, 35, 27, 44, 29, 33, 41, 39
The mode is 41 because it appears twice in the data set, which is more than any other value.
