The interquartile range

Explanation / Answer

The median tipping percentage of 15.25 indicates that half of the tips were below 15.25 % and remaining half were above 15.25% The interquartile range tells us that the middle fifty percent of tips had a range of 6.5%.

the median is the middle value and half of the data will be below this median and remaing half of the data above median.

Q1=first quartile and 25% of data below this Q1 value

Q3=third quartile and 75% of data below this Q3 value

The interquartile range is Q3 minus Q1 i.e. IQR=Q3-Q1
