Question

Quizplus · Accepted Answer

A bell-shaped curve is also known as a normal curve and describes a symmetrical frequency distribution where the majority of observations cluster around the mean, with decreasing frequencies in either direction. A scattergram is a graph used to display the relationship between two continuous variables, a bar graph is used to represent categorical data, and a skewed distribution is asymmetrical with most observations grouped towards one end.
