two histograms showing the number of pets owned by boys and girls in a science class are each skewed left. which measure of variability should be used to describe the data?\nmean\nmedian\nstandard deviation\ninterquartile range
Answer
Brief Explanations:
When data is skewed (in this case left - skewed), the mean and standard deviation are affected by outliers. The median is a measure of central tendency, not variability. The interquartile range (IQR) is less affected by outliers and is a good measure of variability for skewed data.
Answer:
D. interquartile range
