A quantitative variable can be discrete, where only certain values over a range are allowed. If a number of eggs in a basket are being counted, only whole eggs count. There can't be 12.75 eggs. A continuous variable can be any value over a range. How many miles did Roger bike? It ...
Other graphs are designed for quantitative data and highlight how the differences between values provide crucial information. Several top choices are histograms and scatterplots. These graphs display the distribution of a continuous variable and the relationship between two of them, as shown below. You...
