Question

(a) The arithmetic mean of the measurements
(b) The mode
(c) The median

Answer 1

Answer:

Mean can be calculated as
Mean = summation(X)/n = (3.88+4.09+3.92+3.97+4.02+3.95+4.03+3.92+3.98+4.06)/10 = 39.82/10 = 3.982
For median, sort the data from shortest to largest
3.88, 3.92, 3.92, 3.95, 3.97, 3.98, 4.02, 4.03, 4.06, 4.09
Median = (10+1)/2 =5.5th value
Median = (3.97+3.98)/2 = 3.975
Mode for this is 3.92 as its frequency is 2.
