The ages, in years, of randomly selected employees are 34, 41, 28, 35, 27, 44, 29, 33, 41, and 39.
Watch THE MODE TOADS video to learn about measures of center
(4 points)
*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 =
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 =
3)To find the MODE, we will find the value that repeats the most.
MODE =
4)To find the MEAN, we will add up the values and divide by the number of data points.
MEAN =
1) Range = 44 - 27 = 17
2) Since there are 10 values, the median will be the average of the 5th and 6th values in the ordered list.
Median = (29 + 33) / 2 = 31
3) The mode is the value that appears most frequently. In this case, the mode is 41.
4) Mean = (34 + 41 + 28 + 35 + 27 + 44 + 29 + 33 + 41 + 39) / 10
Mean = 351 / 10 = 35.1
Therefore, the range is 17, the median is 31, the mode is 41, and the mean is 35.1.
