Mean is calculated by dividing the sum of the data values by the number of data values.
Median is the middle data value, at 50% of the data, where there is an equal probability of data values falling below or above it.
The lower/first quartile is at 25% of the data, or the middle between of the lower half of data.
The upper/third quartile is at 75% of the data, or the middle between the upper half of data.
Hope this helps!
