Q 1 - Find the mean and median of the given data set.

29, 25, 23, 22, 32, 29

### Explanation

Step 1:

Mean of the data = $\frac{(29+25+23+22+32+29)}{6}$ = 26.67

Step 2:

Data set in increasing order − 22, 23, 25, 29, 29, 32

Median of data set = $\frac{(25+29)}{2} =\frac{54}{2}$ = 27

Q 2 - Find the mean and median of the given data set.

42, 40, 40, 47, 41

### Explanation

Step 1:

Mean of the data = $\frac{(42 + 40 + 40 + 47 + 41)}{5}$ = 42

Step 2:

Data set in increasing order − 40, 40, 41, 42, 47

Middle score = 41; Median of data set = 41.

Q 3 - Find the mean and median of the given data set.

70, 68, 56, 62, 56, 66, 56

### Explanation

Step 1:

Mean of the data = $\frac{(70+68+56+62+56+66+56)}{7}$ = 62

Step 2:

Data set in increasing order − 56, 56, 56, 62, 66, 68, 70

Middle score is 62

Median of data set = 62

Q 4 - Find the mean and median of the given data set.

47, 40, 51, 51, 54, 53

### Explanation

Step 1:

Mean of the data = $\frac{(47+40+51+51+54+53)}{6}$ = 49.33

Step 2:

Data set in increasing order − 40, 47, 51, 51, 53, 54

Median of data set = $\frac{(51+51)}{2} = \frac{102}{2}$ = 51
