What does the median represent in a dataset?

Back

The median is the middle value of a dataset when it is ordered from least to greatest. It divides the dataset into two equal halves.

How do you calculate the interquartile range (IQR)?

Back

The interquartile range (IQR) is calculated by subtracting the first quartile (Q1) from the third quartile (Q3): IQR = Q3 - Q1.

What is the significance of the whiskers in a box plot?

Back

The whiskers in a box plot extend from the quartiles to the minimum and maximum values, showing the range of the data outside the interquartile range.

What does a higher median in a box plot indicate?

Back

A higher median indicates that the central tendency of the data is higher, suggesting that more data points are concentrated at higher values.

How can you identify outliers in a box plot?

Back

Outliers in a box plot are typically represented as individual points that fall outside the range defined by the whiskers, often calculated as 1.5 times the IQR above Q3 or below Q1.

What does the first quartile (Q1) represent?

Back

The first quartile (Q1) represents the value below which 25% of the data falls.

How do you interpret the spread of data in a box plot?

Back

The spread of data in a box plot is indicated by the length of the box and the whiskers; a longer box or whiskers suggest greater variability in the data.
