Question

Monica bowled three games. Her scores were 175, 142, and 133. What was her mean, or average, score?

Answer 1

Answer:

Scores= 175, 142, 133

Mean score= Sum of all observations/No of observations

Mean score= 175+142+133/3

Mean Score= 450/3

Mean Score=150

Hence, Monica's mean or average score is 150

Answer 2

Answer:

Monica's Mean score is 150.

Step-by-step explanation:

Mean = Sum of observations / Number of observations.

Mean = $\frac{175 + 142 + 133}{3}$

Mean = $\frac{450}{3}$

Mean = 150

Mean:

The Arithmetic mean in statistics is the same as average in Arithmetic.

The mean of a set of data is found out by dividing the sum of all the observation by the total number of observations in the set of data.

We denote the mean by $\overline{x}$ (read as "x bar" ).

Mean = Sum of observations / Number of observations.

For finding mean, it is not necessary to arrange the given set of data in ascending or descending order.
