Mathematical Interpretation

What is the purpose of a line plot?

• To bake a cake

• To predict the weather

• To write a novel

• To display data points on a number line to show the frequency of values in a dataset.

How can you determine the shape of a distribution?

• Flip a coin

• Look at the mean and median

• Create a histogram or box plot, calculate skewness and kurtosis.

• Ask a friend for their opinion

In a line plot, what does each point represent?

• Each point represents a data value or observation.

• Each point represents a mathematical formula

• Each point represents a color

• Each point represents a random number

Describe the shape of a distribution that is skewed to the right.

• The shape of a distribution that is skewed to the right is uniform

• The shape of a distribution that is skewed to the right is asymmetrical with a longer tail on the right side.

• The shape of a distribution that is skewed to the right is bell-shaped

• The shape of a distribution that is skewed to the right is symmetrical

Explain how outliers can affect the shape of a distribution.

• Outliers have no impact on the shape of a distribution

• Outliers can pull the mean towards them, making the distribution appear skewed or elongated in the direction of the outlier.

• Outliers only affect the median of a distribution

• Outliers always cause the distribution to become perfectly symmetrical

What does a symmetrical distribution look like?

• A symmetrical distribution looks like a bell-shaped curve.

• A symmetrical distribution looks like a zigzag pattern.

• A symmetrical distribution looks like a spiral shape.

• A symmetrical distribution looks like a straight line.

How can you identify the center of a distribution from a line plot?

• Identify the highest point on the line plot

• Choose the point with the most outliers

• Identify the point where the line plot is most concentrated or balanced on both sides.

• Look for the point where the line plot starts

What is the difference between a unimodal and bimodal distribution?

• The difference is in the color they are represented with

• The difference between a unimodal and bimodal distribution is the number of peaks they exhibit.

• Unimodal distributions have a higher mean than bimodal distributions

• Bimodal distributions have a wider range of values than unimodal distributions

How can you use a line plot to compare two sets of data?

• By plotting each set of data on the same graph with different colors or symbols.

• By plotting both sets of data on separate graphs

• By using a scatter plot instead of a line plot

• By connecting the data points with straight lines
