What is a Box and Whiskers plot?
A box and a whisker plot is a diagrammatic graphical representation that shows the spread of numbers in a given dataset. The box shows the Q1, Q3, and IQR (interquartile range); while the whisker gives the min and max values.
From the given dataset:
The minimum value refers to the lowest value in the dataset and this is 4.
The (Q1) first quartile shows the median value of the initial half of the dataset. Here, we have 4,4,5,5,6,9.
Q1 = (5+5)/2
Q1 = 10/2
Q1 = 5
The median is the middle number in the entire dataset
Median = (6+9)/2
Median = 7.5
The (Q3) third quartile shows the median value of the other half of the dataset. Here, we have 10,12,14,14,14,15
Q3 = (14+14)/2
Q3 = 28/2
Q3 = 14
The maximum refers to the highest number of the dataset = 15.
