Question

The weekly salaries of six employees at McDonalds are $140, $220, $90, $180, $140, $200. For these six salaries, determine: (a) the mean (b) the median (c) the mode and (d) the range.

Answer 1

a) Mean = 161.666667

b)Mode = 140

c) Median =160

d) Range =130

Explanation:

Given that the weekly salaries of six employees =$140, $220, $90, $180, $140, $200

Mean =Total number of salaries/ Number of salaries

=$140 +$220 +$90 +$180 + $140 +$200 /6=970/6= 161.666667

Mode = The number with the highest frequency ie the number that occurs most in the listed salaries

$140, $220, $90, $180, $140, $200

Therefore 140 is the mode

Median = The number that occurs in the middle, Now that we have a list of even Numbers, our median would be the sum of the two middle numbers divided by 2 after arranging in ascending order fro least to greatest

$90, $140,$140, $180, $200,$220

Median =$140+ $180 / 2 = 160

Range = The difference between the highest and lowest number in the sample

$220-$90=130
