Question

Ally surveyed 5 classrooms. She wanted to know the number of students in each class who love painting. The data she collected from the 5 classrooms is below. 10,7,9,11,8 The value that could be the best measure of the center of this data is __ ​

Answer 1

Answer:

9

Step-by-step explanation:

Iḿ pretty sure it is 9 because its mostly in the center the other numbers

Answer 2

The best measure of the center of the data is 9.

What is mean?

The mean is the mathematical average of a set of two or more numbers.

What is median?

The median is the middle value in a list ordered from smallest to largest.

Formula for calculating the median

$median= [\frac{(\frac{n}{2} )^{th} term+((\frac{n}{2} +1) )^{th} term}{2} ]$        (for even number of observation)

$median= [\frac{(n+1)^{th} term}{2} ]$                            ( for odd number of observation)

What is mode?

The mode is the value that appears most frequently in the data set.

According to the given question

we have

A data , 10, 7, 9, 11, 8

Number of observation, n = 5   (which is odd)

Arranging the above data in ascending order

7,8,9,10,11

For calculating the median of the data ,substitute value of n in the formula of median for odd number of observation

therefore,

median = (5+1)th term/2

median = 6/2

median =  3rd term i.e. 9

The best measure of the center of this data is 9.
