According to the research conducted by the geologists of University of Texas, the temperatures of soil in 0C at 750 meters deep inside the ground on different locations of earth are mentioned below:
68.4 72.3 58.7 48.3 53.8 73.2 37.9 55.4 42.7 84.6 67.4 58.5 92.4 62.5 87.8
Calculate:
(i) Arithmetic Mean
(ii) Median
(iii) Mode
(iv) Variance
(v) Standard Deviation

Answer 1

By using Excel

(i) Arithmetic Mean = 64.26

=AVERAGE(B2:B16)

(ii) Median = 62.5

=MEDIAN(B2:B16)

(iii) Mode

=MODE(B2:B16)

There is no mode because all the numbers in the set are different.

(iv) Variance = 257.19

=VAR(B2:B16)

(v) Standard Deviation = 16.03

=STDEV(B2:B16)
