Question

Find the mean, median and mode of 3,7,9,11,2,10,5,7,8,7​

Answer 1

Answer:

Step-by-step explanation:

Given data is

3,7,9,11,2,10,5,7,8,7

Mean=3+7+9+11+2+10+5+7+8+7/2

Mean=69/2

Mean=34.5

Median=2

Mode:

Arranging the given data in increasing order

2,3,5,7,7,7,8,9,10,11

Frequency of 7 is maximum

Mode=7

Answer 2

mean=3+7+9+11+2+10+5+7+8+7/ 10
=69/10
=34.5 is the mean
median-
arrange the numbers in ascending order
2,3,5,7,7,7,8,9,10,11
there are two numbers in the middle.
so, 7 + 7 /2
=14/2
=7
the median is 7.
mode is the number which has repeated the most.

so,the mode is 7.
