Box and Whisker Graphs

What does the median represent in a box and whisker graph?

• Sum of all values divided by the number of values

• Middle value of the dataset when arranged in ascending order

• Highest value of the dataset

• Value that occurs most frequently in the dataset

How do you calculate the range in a box and whisker graph?

• Range = Maximum value - Minimum value

• Range = Maximum value * Minimum value

• Range = Maximum value / Minimum value

• Range = Maximum value + Minimum value

What does the interquartile range show in a box and whisker graph?

• It shows the range of the middle 50% of the data.

• It shows the standard deviation of the data set.

• It shows the mean of the data set.

• It shows the maximum value in the data set.

How can you recognize skewness in a box and whisker graph?

• Ensure the box is perfectly symmetrical.

• Check if the median line within the box is not centered.

• Check if the whiskers are of equal length.

• Look for outliers beyond the whiskers.

In a box and whisker graph, where is the median located?

• Outside the box

• Above the box

• Below the box

• Inside the box

If the range in a box and whisker graph is large, what does it indicate?

• The data is evenly distributed

• The data is missing outliers

• The data is spread out over a wide range of values.

• The data is concentrated in a narrow range

What is the significance of the interquartile range in a box and whisker graph?

• It represents the mean of the data points.

• It shows the spread and distribution of the central data points.

• It indicates the maximum value in the dataset.

• It shows the frequency of outliers.

What type of skewness is present if the box in a box and whisker graph is closer to the lower whisker?

• Negative skewness

• Symmetric skewness

• No skewness

• Positive skewness

What does a median closer to the lower quartile suggest in a box and whisker graph?

• Negatively skewed distribution

• Outlier-free dataset

• Normal distribution

• Positively skewed distribution

How is the range calculated in a box and whisker graph?

• Range = Maximum Value - Minimum Value

• Range = Maximum Value + Minimum Value

• Range = Maximum Value * Minimum Value

• Range = Maximum Value / Minimum Value
