**Mean , Median and Mode**

.They are important for their own purposes depending on the analysis you want to carry out .

. Mean is very subjective as there is an outlier that can severely affect the data .

. Median is the 50% mark , letting you see how the performance of a group is .

. Mode lets you see the most popular set of data and the trends .

**Box Plot**

Lower percentile - Underperforming

Upper percentile - Excelling > Able to plot data using the 2 points

. Box Plots let you see performances better for evaluation ( Better than Ogive)

- It is easier to see if the data is skewed ( Biased or shifted towards) based on where Q1 , Q2 and Q3 is

- Look at interquartile range and range to determine spread and performance as a whole .

To transfer the box plot into a cumulative frequency against value graph ,

a) Plot it vertically using Q1 , Q2 and Q3 as points

b) Plot it horizontally to see how everyone is performing .
