Measurement Data on Line Plots

What is the purpose of a line plot?

• To represent the geographical distribution of a population

• To display the average of a set of data points

• To show the relationship between two categorical variables

• To display the distribution of a continuous variable over a specific range.

In the line plot, which number appears most frequently?

• The number that appears most frequently is 2.

• The number that appears most frequently is 8.

• The number that appears most frequently is 10.

• The number that appears most frequently is 5.

Identify any outliers in the following line plot:

• The data point at x=3 is an outlier.

• The data point at x=7 is an outlier.

• The data point at x=5 is an outlier.

• The data point at x=10 is an outlier.

Create a line plot for the data set {3, 3, 4, 4, 4, 5, 5, 6, 7, 8}.

• The line plot will show a line decreasing from 3 to 8

• The line plot will show a line with random peaks and valleys

• The line plot will show a line rising steadily from 3 to 8 with some repeated values at certain points.

• The line plot will show a horizontal line at y=4

How does a line plot help in understanding the spread of a data set?

• By showing the range and frequency of each data point.

• By indicating the total sum of all data points.

• By highlighting the data points that are outliers.

• By displaying the data points in ascending order only.

For the data set {1, 2, 2, 3, 4, 5, 5, 5, 6}, what is the effect of an outlier, such as 10, on the line plot?

• It extends the range of the plot, potentially distorting the visual representation of the data distribution.

• It has no effect on the line plot as outliers are not represented.

• It decreases the overall frequency of the data set.

• It shifts the median of the data set to a higher value.

Explain the concept of frequency in line plots.

• Frequency refers to the speed at which data points are connected by lines.

• Frequency indicates the angle at which lines intersect on the plot.

• Frequency is the measurement of the distance between each data point.

• Frequency represents the number of times a value appears in the data set.

How do line plots show the distribution of a data set?

• By displaying the maximum value of the data points

• By displaying the frequency of each data point along a number line.

• By displaying the average of the data points

• By displaying the median of the data points
