TASK
Discuss the following by framing the step – wise calculations.
Mean – Mean refers to the average of all the numbers or observations. It is one of the
three averages of the central tendency (Alallawi, and et.al., 2021). For instance, if person playing
a cricket match scores runs in its previous 5 innings which are 25, 30, 35, 40, 45 than the
average mean of that person is 35.
In order to calculate the mean its steps are mentioned below:
 1st Step – Examine all the numbers or observations given.
 2nd Step – Add all the above values that are given.
 3rd Step – Tally the entire number of the observation.
 4th Step – Division of the sum of the observation to all the number of the values.
Sum of observation/ Total number of observation = Mean.
793 / 10 = Mean.
Mean = 79.3
Median – It refers to the value that is derived after arrangement of the given data in
descending or ascending way. After that the middle value of the series is refers to the median of
the series (Karakolidis, and et.al., 2021).
In order to calculate the median its steps are mentioned below:
 1st Step – Initially, numbers need to be arranged in the ascending order which means
smallest number to the largest.
 2nd Step – After that it is required to calculate the number of the observation either if it is
even or odd.
 3rd Step – If the number is Even, then the formula which is being utilised is (N/2 )
 4th Step – If the numerical is in odd then the formula will be ( (N+1)/2 )
 5th Step - The following outcome is the place of the median.
Median = ( N+1)/ 2 = if ' N' is odd number
(N/2 ) = If ' N' is even number
