Understanding Stem-and-Leaf Plots and Statistical Measures

What is the first step in creating a stem-and-leaf plot?

• Subtract the smallest number from the largest

• Organize the data in ascending order

• Calculate the mean of the data

• Find the mode of the data

When constructing a stem-and-leaf plot, what should you do if there is a gap in the data?

• Skip the missing number

• Leave the gap empty

• Include the missing number in the stem

• Ignore the gap and continue

How do you calculate the mean of a dataset?

• Subtract the smallest number from the largest

• Add all numbers and divide by the number of data points

• Find the middle number in the dataset

• Identify the most frequently occurring number

What is the median in a dataset?

• The difference between the largest and smallest numbers

• The middle number when data is ordered

• The most frequently occurring number

• The average of all numbers

What is the range of a dataset?

• The difference between the largest and smallest numbers

• The sum of all numbers

• The middle number when data is ordered

• The most frequently occurring number
