Question

the scores in a test of 10 students in as follows:

31, 36,35,40, 39,33,40,30,39,37
Find the mean of this data.​

Answer 1

Answer:

36

Step-by-step explanation:

• mean=sum of observation÷total no. of observation
• mean=31+36+35+40+39+33+40+30+39+37÷10
• =360÷10=36

Answer 2

Answer:

If the scores in a test of students are 31,36,35,40,39,33,40,30,39 and 37 then the mean of this data is 36

Step-by-step explanation:

Given the scores in test of 10 students as follows

S1= 31

S2 = 36

S3 = 35

S4 = 40

S5 = 39

S6=33

S7=40

S8=30

S9=39

S10= 37

Mean of this data = sum of scores of 10 students/ total number of students

=$\frac{S1+S2+S3+S4+S5+S6+S7+S8+S9+S10}{10} \\\\=\frac{31+36+35+40+39+33+40+30+39+37}{10}$

=$\frac{360}{10} \\\\=36$

Hence mean of the scores of 10 students is 36
