Question

Jake's test scores for the first term of chemistry class were 78, 68, 73, 94, and 62. Which of the measures of central tendency would make Jake's test scores seem as high as possible? *

Mean
Median
Mode
Range

Answer 1

Mean is the highest average out of all = 75

Explanation:

The "range" of a list a numbers is just the difference between the largest and smallest values.

Ans The range = 94-62 = 32

Find the mean, median, mode, and range for the following list of values:

62, 68, 73, 78, 94

The mean is the usual average, so you add and then divide:

(62, 68, 73, 78, 94 ) ÷ 5 = 75

Ans = mean of 75

The median is the middle value, so first I'll have to rewrite the list in numerical order:

62, 68, 73, 78, 94

Ans = median of 73

There are five numbers in the list, so the middle one will be the 3rd number.

The mode is the number that is repeated more often than any other, so 70 if data was in 10's would be the mode.

range: 32

mean: 75

median: 73

mode: 0

Answer 2

Mean

Explanation:

For the mean, his score is a 75 (78+68+73+94+62/5)

For the median, his score is a 73 (in order: 62 68 73 78 94, the middle number is the median)

There is no mode because there are no repeating numbers

For the range, his score is a 32. (highest - lowest: 94-62)

This should be right, hope it helps. :)
