The marks of 12 students in mathematics is as follows:

47, 73, 39, 46, 37, 35, 29, 43, 41, 49, 35, 30

Study the above data and answer the question.

Mean of the given data is.

42

Mean/ average = \(\frac{sum\;of\;observations}{total\;observations}\)

Sum = 47 + 73 + 39 + 46 + 37 + 35 + 29 + 43 + 41 + 49 + 35 + 30 = 504

Mean/ average = \(\frac{504}{12}\) = 42
