Box and Whisker Plot Concepts

The video tutorial covers measures of central tendency and box and whisker plots using Desmos. It explains how to calculate mean, median, and mode, and how to create and analyze box and whisker plots. The tutorial also covers identifying outliers and calculating the interquartile range (IQR) and bounds. The video provides step-by-step instructions for using Desmos to perform these statistical analyses.

What is the first step in analyzing measures of central tendency using Desmos?

• Drawing a graph

• Calculating the mode

• Entering a data set

• Finding the range

Which column is used for entering data in Desmos for calculating the mean?

• Y column

• X column

• W column

• Z column

How do you calculate the mean in Desmos?

• Select 'range' from functions and type y1

• Select 'median' from functions and type y1

• Select 'mode' from functions and type y1

• Select 'mean' from functions and type y1

What is the limitation of Desmos when calculating measures of central tendency?

• It cannot calculate the mode

• It cannot calculate the mean

• It cannot calculate the range

• It cannot calculate the median

What is suggested for finding the mode manually?

• Using a computer program

• Using a tally mark system

• Using a graph

• Using a calculator

What is the first step in creating a box and whisker plot in Desmos?

• Finding the mean

• Entering a data set

• Drawing the plot

• Calculating the range

What is the purpose of finding Q1 and Q3 in a box and whisker plot?

• To calculate the mean

• To determine the range

• To find the interquartile range

• To identify the mode

How is the interquartile range (IQR) calculated?

• Subtracting Q1 from Q3

• Adding Q1 and Q3

• Multiplying Q1 and Q3

• Dividing Q1 by Q3

What is the significance of the upper and lower bounds in a box and whisker plot?

• To find the mean

• To identify outliers

• To calculate the median

• To determine the mode

What is considered an outlier in a box and whisker plot?

• A value equal to the mean

• A value outside the upper and lower bounds

• A value within the range

• A value equal to the median
