Question

4. Find the mean, median and mode of the following marks of 15 students
screening test (out of 20): 2,5,3,3,0, 18, 5, 7, 11, 15, 1, 13, 0, 8,0​

Answer 1

Answer:

Mean = 6.67, Median = 5, Mode = 0

Step-by-step explanation:

Mean =  $\frac{2 + 5 + 3 + 3 + 0 + 18 + 5 + 7 + 11 + 15 + 1 + 13 + 0 + 8 + 0}{15}$ = $\frac{91}{15}$ = 6.67

Median = 0, 0, 0, 1, 2, 3, 3, 5, 5, 7, 8, 11, 13, 15, 18 = 5

Mode = 0, 0, 0, 1, 2, 3, 3, 5, 5, 7, 8, 11, 13, 15, 18 = 0

Answer 2

Answer:

mean=2+5+3+3+0+18+5+7+11+15+1+13+0+8+0/20

91/20

mode=0 is occuring 3 times

median=0,0,0,1,2,3,3,5,5,7,8,11,13,15,18

here median is 5
