Visualizations of Data Test

A majority of the data is on the low end of the range.

Pie charts represent the percentages of each categorical data point.

Shape, direction, and strength.

Outliers are defined as any value that is farther away from the first or third quartile than 1.5 times the interquartile range (IQR).

False, the whiskers may not extend to the minimum and maximum values.

The interquartile range (IQR) is the difference between the first quartile (Q1) and the third quartile (Q3) of a data set.

A scatterplot is used to visualize the relationship between two quantitative variables.

The shape of a scatterplot indicates the type of relationship (linear, nonlinear, etc.) between the variables.

The direction indicates whether the relationship between the variables is positive, negative, or neutral.

The strength refers to how closely the data points cluster around a line of best fit.
