How do you interpret the height of bars in a histogram?

Back

The height of each bar in a histogram represents the frequency (count) of data points that fall within the corresponding range (bin).

What is a boxplot (box-and-whisker plot)?

Back

A boxplot is a standardized way of displaying the distribution of data based on a five-number summary: minimum, first quartile (Q1), median, third quartile (Q3), and maximum.

What does the median represent in a boxplot?

Back

The median is the middle value of a data set when it is ordered from least to greatest, dividing the data into two equal halves.

What are quartiles in a boxplot?

Back

Quartiles are values that divide a data set into four equal parts: Q1 (25th percentile), Q2 (50th percentile or median), and Q3 (75th percentile).

How do you find the range of a data set?

Back

The range is calculated by subtracting the minimum value from the maximum value in the data set.

What does it mean if a histogram is skewed to the right?

Back

A right-skewed histogram indicates that the majority of the data points are concentrated on the left side, with a few larger values stretching the tail to the right.

Front

What does it mean if a histogram is symmetric?

Back

A symmetric histogram indicates that the data is evenly distributed around the center, with similar frequencies on both sides.

Front

How can you determine the mode from a histogram?

Back

The mode is the value or range with the highest bar in the histogram, indicating the most frequently occurring data points.

What is the interquartile range (IQR)?

Back

The interquartile range (IQR) is the difference between the third quartile (Q3) and the first quartile (Q1), representing the middle 50% of the data.
