Histograms & Dot Plots Quiz

What is the main difference between histograms and dot plots?

• Histograms can only be used for quantitative data, while dot plots can be used for both quantitative and qualitative data.

• Histograms show frequency distributions of a set of data, while dot plots show each data point value.

• Dot plots are used for large data sets, while histograms are used for smaller data sets.

• There is no difference; they are just different terms for the same type of graph.

A histogram displaying the scores of a class on a math test shows a peak at 80-89 range with no bars at 0-59 range. What does this indicate?

• No students scored between 0 and 59.

• Most students scored between 80 and 89.

• The test was too difficult for the class.

• The test was too easy for the class.

When creating a dot plot, what is the correct way to represent the data points?

• Place a dot for each category of data.

• Stack dots vertically for each data point in a category.

• Place a single dot for each data point along a horizontal scale.

• Connect the dots with lines.

If a histogram has bars that are all of nearly the same height, what does this indicate about the distribution of the data?

• The data is skewed to the left.

• The data is skewed to the right.

• The data is uniformly distributed.

• The data cannot be determined from the histogram alone.

In interpreting a dot plot, what does a clustering of dots at one location on the plot suggest?

• There is a high variability in the data.

• There is a low variability in the data.

• The data is uniformly distributed.

• The data cannot be interpreted without a histogram.

How can outliers be identified in a histogram?

• By the bars that are significantly taller than the others.

• By the bars that are significantly shorter than the others, separated from the main group.

• Outliers cannot be identified in a histogram.

• By the gaps between the bars.

When creating a histogram, what does the width of each bar represent?

• The frequency of the data points.

• The range of data points within each interval.

• The median of the data points.

• The total number of data points.

A dot plot shows the number of books read by students in a class. If one student read 15 books, and this is the highest number on the dot plot, how is this represented?

• By a dot placed highest on the vertical scale.

• By a dot placed furthest to the right on the plot.

• By a larger dot than the others.

• By more dots stacked vertically at the number 15.

What is an advantage of using a histogram over a dot plot when representing data?

• Histograms can show each individual data point.

• Histograms are better for small data sets.

• Histograms can more effectively display the distribution of large data sets.

• Histograms require less space to represent the data.

If a dot plot shows several dots at the minimum and maximum with few dots in between, what can be inferred about the data?

• The data is uniformly distributed.

• The data has a high variability.

• The data is skewed.

• The data shows a bimodal distribution.
