Question

You work at a local grocery store. Your paychecks over the past 6 weeks were $56.05, $41.50, $22.50, $52.90, $49.85 and $31.00. Find the mean, median and mode.

Answer 1

Mean is the average of all the paychecks, so it will be: (56.05 + 41.50 + 22.5 + 52.9 + 49.85 + 31)/ 6

The mean is: $42.30. So on average she earns $42.30 each week.

We can find the median by arranging from smallest to larges so: 22.5, 31, 41.5, 49.85, 52.9 and 56.05. Since we have an even number of entries, we will take the average of the middle two entries: (41.5 + 49.85)/2

So the median is: 45.68 (rounded to the nearest tenth)

Mode is the number that appears the most in a given set. In this set we can see, that no number is repeated. Therefore there is no mode.
