What is the purpose of ordering the data from least to greatest when calculating the interquartile range?

• To simplify the calculation of the median

• To calculate the mean more accurately

• To find the mode of the data

• To prepare data for graph plotting

What does the mean absolute deviation tell us about a dataset?

• The difference between the highest and lowest values

• The most common value in the dataset

• The total range of the dataset

• The average distance each data point is from the mean

If the mean absolute deviation is small, what can be inferred about the dataset?

• There is no variation in the data

• Data points are closely packed

• Data points are widely spread out

• The dataset contains outliers
