Unit 1 FGHIJ

How does the presence of an outlier affect the shape of a boxplot?

• It makes the boxplot symmetrical.

• It skews the boxplot and affects the spread of the data.

• It has no effect on the boxplot.

• It shortens the whiskers of the boxplot.

What conclusion can be drawn if the median of a boxplot is closer to the lower quartile?

• The data is skewed to the right.

• The data is skewed to the left.

• The data is symmetrical.

• The data has no outliers.

When comparing two boxplots, what does it indicate if one has a longer interquartile range (IQR) than the other?

• The data set with the longer IQR has less variability.

• The data set with the longer IQR has more variability.

• Both data sets have the same variability.

• The data set with the longer IQR has more outliers.

Which graphical representation is best for showing the distribution of a single data set with outliers?

• Pictograph

• Bar graph

• Boxplot

• Circle graph

What is a common misleading component in a bar graph?

• Unequal bar widths

• Consistent scale

• Equal spacing between bars

• Labeled axes

If an outlier is removed from a data set, what happens to the range of the boxplot?

• The range increases.

• The range decreases.

• The range remains the same.

• The range becomes zero.

In a boxplot, if the median is closer to the upper quartile, what can be inferred about the data?

• The data is skewed to the left.

• The data is skewed to the right.

• The data is symmetrical.

• The data has no variability.

When comparing two boxplots, what does it mean if one has a higher median than the other?

• The data set with the higher median has more variability.

• The data set with the higher median has a higher central tendency.

• Both data sets have the same central tendency.

• The data set with the higher median has more outliers.

Which graphical representation is best for comparing the frequency of categories in a data set?

• Line graph

• Histogram

• Bar graph

• Boxplot

What is a misleading component in a line graph?

• Consistent intervals on the x-axis

• A broken y-axis

• Labeled data points

• A title
