How do you find the median in a data set?

Back

To find the median, arrange the data in numerical order and identify the middle value. If there is an even number of observations, the median is the average of the two middle values.

What does the interquartile range (IQR) represent?

Back

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

What does a greater median indicate in a data set?

Back

A greater median indicates that the central value of the data set is higher, suggesting that, on average, the values in that data set are larger.

How do you calculate 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 two data sets have the same range?

Back

If two data sets have the same range, it means that the difference between their maximum and minimum values is the same, indicating similar spread.

What is the significance of outliers in box plots?

Back

Outliers are data points that fall significantly outside the range of the rest of the data. They can indicate variability in the data or errors in data collection.

Front

How can you identify the median from a box plot?

Back

The median is represented by the line inside the box of the box plot, dividing the box into two parts.
