Question

Your math students are learning about histograms. Histograms similarly use bars to compare data, but the independent variable is a continuous variable that has been "binned" or _________________.

a) Categorized
b) Grouped
c) Rounded
d) Discretized

Answer 1

In histograms, the independent variable is a continuous variable that has been grouped into classes. Histograms display quantitative measures and they represent the shape, center, and spread of data. There can be different conventions regarding how boundary values are counted in class intervals. The correct option is b. grouped

Step-by-step explanation:

In a histogram, the independent variable is a continuous variable that has been "binned" or grouped. Essentially, to construct a histogram, you decide on the number of bars, also called classes, to represent the data. These bars or classes are often between five to 15 for clarity. The width of each bar, known as the bin size, might be calculated by dividing the range of the data by the desired number of bins. Consistency is important when assigning data values to each class interval.
