If the weights of 5 students are given as 38kg,41kg,36kg,39kg and 41 kg, find the mean and range of the given data.
Mean = Sum of all observations / No. of observations
= (38+41+36+39+41) / 5 = 195 / 5
= 39
Therefore the mean of the data is 39 kg
Range of the Data = maximum value - minimum value = 41 - 36 = 5
Therefore the Range of the given data is 5.
