Question

Could you draw a box plot for class 2? Class 2: 70, 77, 79, 82, 84, 84, 84, 84, 86, 86, 86, 86, 86, 87, 88, 88, 88, 88, 89, 90

Answer 1

In making a box plot, we need five (5) data. These are the minimum, quartile 1, median, quartile 3, and maximum data.

In the given Class 2 Data, the details are:

1. Minimum Data - 70

2. Quartile 1 - 84

3. Median - 86

4. Quartile 3 - 88

5. Maximum Data - 90

Let's now draw the box plot.

1. Draw a number line from 70 to 90 or from 60 to 100. The number line depends on you.

2. Plot the 5 data on the number line.

3. After plotting, draw a box from Q1 to Q3.

4. Cut the box created in half by drawing a vertical line through the median.

5. Draw whisker or line from minimum to Q1 and from Q3 to maximum.

See the final box plot below.
