Understanding Dot Plots, Histograms, and Box Plots

What shape does a normal distribution have in a dot plot?

• Bell-shaped curve

• Irregular shape

• Straight line

• Scattered dots

What indicates a skewed right distribution in a histogram?

• Symmetrical bars

• A tail on the right side

• Uniform bar heights

• A tail on the left side

Why can't the mean be accurately found using a histogram?

• Because it only shows the median

• Because histograms cannot show distributions

• Because individual data points are not distinguishable

• Because it shows only the mode

What does the median represent in a data set?

• The most frequent value

• The average of all values

• The difference between the highest and lowest values

• The middle value when data is ordered

How is the mode identified in a histogram?

• The shortest bar

• The last bar

• The tallest bar

• The first bar

What is a drawback of using histograms to find the median?

• They show too much detail

• They are too complex to understand

• They cannot show exact values

• They only display the mode

What does Quartile 1 represent in a box plot?

• The median of the dataset

• The maximum value

• The 25th percentile

• The minimum value

Which part of the box plot indicates the range of the middle 50% of the data?

• The space between Quartile 1 and Quartile 3

• The space between the minimum and maximum

• The whiskers

• The median line

In which plot is it easiest to identify quartiles?

• Histogram

• None of the above

• Box plot

• Dot plot

What is the benefit of using a box plot to represent data?

• It clearly shows the distribution's skewness

• It displays individual data points

• It can accurately calculate the mean

• It easily identifies quartiles and the median
