Question

5. The numbers of students present in a class on 16 days are 30, 23, 24, 26, 28, 24, 25, 28,
23, 29, 27, 23, 24, 28. 27 and 23. Find the mean, median and mode of the distribution


​

Answer 1

Answer:

25

Step-by-step explanation:

3,25,28,25,16,23,17,22,25,25

Total no. of terms =10

Sum of data =23+25+28+25+16+23+17+22+25+25=229

Therefore,

Mean of given data =  

10

229

​  

=22.9

Now, since no. of terms is even.

Therefore,

Median of given data =  

2

(  

2

n

​  

)  

th

 term +(  

2

n

​  

+1)  

th

 term

​  

 

=  

2

16+23

​  

 

=  

2

39

​  

=19.5

Since 25 has occured most frequently in the given set of data.

Therefore,

Mode of data =25

Answer 2

Step-by-step explanation:

mean is 1.6

median is 2

mode is 0
