Question

3. Determine (i) the mode, (ii) the median and (iii) the mean for each of the following sets of data.
(a) 1,16, 11, 6, 11, 8, 14, 11, 21​

Answer 1

Answer:

Data in ascending order :-

1 , 6 , 8 , 11 , 11 , 11 , 14 , 16 , 21

Mode = 11

Median = n = no of term

n is odd

$(\frac{n}{2})th \: term + 1 = \frac{9}{2} + 1 = \\ \: \frac{10}{2} = 5th \: term \: in \: ascending \: order \\ = 11$

Mean = Sum of numbers

Total numbers

$\frac{1+6+8+11+11+11 + 14+ 16+21}{9} \\ = \frac{99}{9} = 11$

Answer 2

Step-by-step explanation:

arrange in ascending order

1,6,8,11,11,11,14,16,21

MODE=11

MEDIAN =n=number of term

n=odd

(n/2)+1=9/2+1

10/2

5th ascending order

MEAN=sum of numbers

total number

1+6+8+11+11+11+14+16+21
