Question

A meteorologist is studying the monthly rainfall in a section of the Brazilian rainforest. She recorded the monthly rainfall, in inches, for last year. They were:

10.4, 10.3, 11.7, 11.1, 8.0, 4.4, 2.6, 1.8, 2.5, 4.4, 7.3, 9.5

Calculate the following for the data set:

Answer 1

Mean = 7

Median = 7.65

Mode = 4.4

Range = 9.9

Explanation:

Answer 2

Mean = 7

Median = 7.65

Mode = 4.4

Range = 9.9

Explanation:

The question is incomplete as it doesn't state what to find. Lets complete the question first. The complete question states that:

Calculate the following for the data set

Mean

Median

Mode

Range

A) Mean

Mean = sum of values/ total number of values

Mean = 84/12

Mean = 7

B) Median

Arrange the data in ascending order

1.8, 2.5, 2.6, 4.4, 4.4, 7.3, 8.0, 9.5, 10.3, 10.4, 11.1, 11.7

Median = Average of middle values

Median = (7.3+8.0) / 2

Median = 7.65

C) Mode

Mode = number which appears most = 4.4

D) Range

Range = Max value - Min value

Range = 11.7 - 1.8

Range = 9.9
