MATHS - Statistics - Stem and Leaf Plots

The video tutorial explains how to create and interpret stem-and-leaf plots, a method for displaying data. It covers the basics of splitting data into stems and leaves, creating a key, and ordering data. The tutorial includes examples with whole numbers and decimals, and provides practice exercises to reinforce learning.

What is the purpose of a stem-and-leaf plot?

• To sort data alphabetically

• To display data in a visual format

• To calculate the average of data

• To find the median of data

In a stem-and-leaf plot, what does the 'stem' represent?

• The last digit of a number

• The first digit or digits of a number

• The decimal part of a number

• The total sum of the data

When dealing with larger numbers, how is the stem determined?

• By using the middle digit

• By using the sum of all digits

• By using the last digit

• By using the first two digits

What additional step is necessary when creating a stem-and-leaf plot for larger numbers?

• Adding a title

• Including a key

• Using a different color

• Calculating the mean

How are decimals represented in a stem-and-leaf plot?

• By ignoring the decimal point

• By rounding to the nearest whole number

• By breaking numbers into units and tenths

• By using the whole number as the stem
