The marks obtained by 10 students in a test are 15,75,33,67,76,54,39,12,78,11. Find the arithmetic mean.
Mean of the data set:
The mean of the given data is the sum of all values divided by the total number of values.
∴Mean=15+75+33+67+76+54+39+12+78+1110⇒=46010⇒=46
Hence, the arithmetic mean is 46.
