Answer 2

Answer:

Mode = 14

Median =14

Tip :

Mode: mode is maximum occurring observation.

Median: Median of a given data is the middle observation when the data is arranged in an ascending or descending order.

Given :11, 15, 17, 13, 15, 12, 14, 13, 15, 13,20.​

To Find: find the mode and median of the data

Step-by-step explanation:

First, arrange the data in ascending order.

11,12,13,13,13,14,15,15,15,17,20

Mode : The number which appears most often in a set of numbers is called mode.

Number        no. of times occur

11                           1

12                          1

13                          3

14                          1

15                          3

17                           1

20                         1

13 and 15 occurred 3 times.

So, the mode of the given data is $\frac{13+15}{2}=14$

Median: the mid-value of the data is called the median.

11,12,13,13,13,14,15,15,15,17,20  

Total numbers = 11

Mid value is 6th term = 14

Thus the median is 14
