Histogram and Skew Quiz

What is a histogram?

• A histogram is a type of bar chart used to display data in intervals.

• A histogram is a statistical measure that represents the average value of a dataset.

• A histogram is a graphical representation of the distribution of a dataset.

• A histogram is a visual representation of the relationship between two variables.

Name the three types of histograms.

• stacked histograms

• bar histograms

• frequency histograms, relative frequency histograms, and cumulative frequency histograms

• percentage histograms

What is skewness in histograms?

• Measure of dispersion.

• Measure of central tendency.

• Measure of symmetry.

• Measure of asymmetry

How is skewness measured in histograms?

• Mean

• Median

• Variance

• Third standardized moment

What does a positive skewness indicate in a histogram?

• The distribution is symmetric.

• The tail of the distribution is skewed to the right.

• The data is normally distributed.

• The tail of the distribution is skewed to the left.

What does a negative skewness indicate in a histogram?

• The majority of the data is concentrated towards the right side of the histogram.

• The histogram is symmetrical.

• The data is evenly distributed across the histogram.

• The majority of the data is concentrated towards the left side of the histogram.

What is a symmetrical histogram?

• A symmetrical histogram is a graphical representation of data where the distribution of values is concentrated in the middle and tapers off towards the edges.

• A symmetrical histogram is a graphical representation of data where the distribution of values is balanced on both sides of the central axis.

• A symmetrical histogram is a graphical representation of data where the distribution of values is random and does not follow any pattern.

• A symmetrical histogram is a graphical representation of data where the distribution of values is skewed towards one side of the central axis.

How can you determine if a histogram is symmetrical?

• Visually inspect the histogram for a mirror image on either side of the central axis.

• Calculate the mean and median of the histogram and compare them.

• Count the number of peaks in the histogram.

• Measure the skewness of the histogram.

What is the shape of a symmetrical histogram?

• Square-shaped curve

• Triangle-shaped curve

• Bell-shaped curve

• Sine wave-shaped curve

Can a histogram have more than one mode? Explain.

• Yes, but it is very rare for a histogram to have more than one mode.

• No, a histogram can have multiple peaks but not multiple modes.

• Yes

• No, a histogram can only have one mode.
