In statistics mean median mode and range are the basic concepts.
Mean is the average of a given sample / population
Median is the middle number in a sequence of number / samples
Mode is the highest occurring sample / number
Whilst the Range is the difference between the highest and the lowest of the numbers given in the sample
With that information Mode can be concluded since
Mean = 24 (Average)
Median = 24 (Middle Number)
Mode is also 24, if we have two sample number of 24 the mean is 24, with that, we also have a median of 24
