Question

Airport parking the number of short-term parking spaces at 15 airports is shown   

find the following mean, median, mode, midrange 


750 3400 1962 700 203
900 8662 260 1479 5905
9239 690 9822 11321 2516

Answer 1

Mean = add all the numbers up , then divide how many number there is all together

Median = put the numbers lowest to highest and find the middle number

Mode = the most common number

Mid range = not sure but range = biggest number - lowest number

Answer 2

Mean = 3853.93

Median = 1962

Mid range = 5762

Explanation:

We are given the following information in the question:

750, 3400, 1962, 700, 203, 900, 8662, 260, 1479, 5905, 9239, 690, 9822, 11321, 2516

`Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}`

Mean =
`(57809)/(15) = 3853.93`

`Median:\\\text{If n is odd, then}\\\\Median = \displaystyle(n+1)/(2)th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle((n)/(2)th~term + ((n)/(2)+1)th~term)/(2)`

Sorted data: 203, 260, 690, 700, 750, 900, 1479, 1962, 2516, 3400, 5905, 8662, 9239, 9822, 11321

Since n is odd,

Median =
`8^(th)\text{ term} =1962`

Mode is the observation with highest frequency. But in this data all the values appeared once.

Mid range =

`\displaystyle\frac{\text{Highest value + Lowest value}}{2} = (11321+203)/(2) = 5762`
