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
Range = 17
2)To find the MEDIAN, we will find the center value. If there are 2 center values, you must find the mean of the 2 center values.
MEDIAN = ___
Since we have 10 values, the median will be the average of the 5th and 6th values when ordered from least to greatest.
When we order the values: 27, 28, 29, 33, 34, 35, 39, 41, 41, 44
The median age is (34 + 35) / 2 = 34.5
3)To find the MODE, we will find the value that repeats the most.
MODE = ___
In this set of ages, the mode is 41 because it appears twice, which is more than any other value in the list.
MODE = 41
4)To find the MEAN, we will add up the values and divide by the number of data points.
MEAN = ____
MEAN = (34 + 41 + 28 + 35 + 27 + 44 + 29 + 33 + 41 + 39) / 10
MEAN = 351 / 10
MEAN = 35.1
Therefore, the mean age of the employees is 35.1 years.
