## Problem 752

The distance traveled to 7 different swim meets are given below:

15,30,32,52,75,77

Find the median distance traveled.

** **

**Solution:-**

52 miles

## Problem 609

Find the median of the following set of numbers.

33, 72, 23, 27, 77, 68, 85

**Solution:-**

First arrange the values in ascending order which is given bellow

23 , 27, 33, 68, 72, 77, 85

When the number of values of odd then medain = th term

Where n=number of terms

So here medain==4 th term

4 th term is 68

## Problem 608

Find the median of the following set of numbers.

52, 25, 55, 51, 67, 59

**Solution:-**

First arrange the values in ascending order which is given bellow

25, 51, 52, 55 , 59, 67

When the number of values of even then medain =avarge of th term and ()+1 th term

Where n=number of terms

So here medain=

3 rd term is 52

4 th term is 55

Median= =

## Problem 607

Fiona kept the following records of her phone bills for 12 months:

$55, $50, $64, $54, $71, $57, $55, $48, $66, $71, $59, $70

Find the mean and median of Fiona’s monthly phone bills.

**Solution:-**

First arrange the values in ascending order which is given bellow

$48, $50, $54, $55,$55,$57,$59,$64,$66,$70,$71,$71

Mean=sum of terms /number of terms

Sum of terms=48+50+54+55+55+57+59+64+66+70+71+17=720

Number of terms=12

So mean=720/12=$60

When the number of values of even then medain =avarge of n/2 th term and (n/2)+1 th term

Where n=number of terms

So here medain=[12/2 + (12/2)+1]/2=(6 th term+7 th term)/2

6 th term is $57

7 th term is $59

So median=(57+59)/2=$58

## Problem 603

Find the median of the following set of numbers.

4, 5, 6, 9, 11

**Solution:-**

First arrange the values in ascending order which is given bellow

4, 5, 6, 9, 11

When tha number of values of odd then medain = th term

Medain==3 th term

3 th term is 6

## Problem 426

Find the median of the following set of numbers.

4, 5, 6, 9, 11

**Solution**

First arrange the values in ascending order which is given bellow solution:-

4, 5, 6, 9, 11

When tha number of values of odd then medain = th term

Medain==3 th term

3 th term is 6

## Median

Median

**Odd Number of Entries**

8, 7, 4, 3, 1

The median is a middle term “4”.

** **

**Even Number of Entries**

2, 3, 4, 7, 9, 12

The median is average value of two middle terms

= 5.5
