Mean Calculation
Formula:
The mean is calculated using the following formula:
Calculation:
Median Calculation
Formula:
(a) The data needs to be sorted first in ascending order:
(b) After sorting the data, the median is calculated using the following formula:
Calculation:
Here, since n= 15 is odd. Hence, median is th observation in the dataset which is 8th observation.
Median =50
Mode Calculation
Formula:
The mode is that value in the dataset which has the highest frequency.
Calculation:
Here, in the dataset it can be seen that 30, 44 and 50 these values have the highest frequency since all of them occur two times in the dataset. Hence, the dataset is trimodal since this data has three modes 30,44 and 50.
Conclusion:
(a) Mean of the dataset is 60.2 which implies that the centre of the dataset lies at 60.2.
(b) Median also tells about the centre of the dataset. Median of the dataset is 50 which says that half of the given data points are less...
