The scatter plot at the left shows the results or simulating a coin toss 150 times. Notice that, as the number of tosses increases, the probability of tossing a head gets closer and closer to the theoretical probability of 0.5.

Guided Practice 4: Perpendicular Line Through a Given Point Write an equation in slope-intercept form for the line that passes through and is perpendicular to the graph of . Lesson 4-5 Scatter Plots and Lines of Fit Objectives: I can investigate relationships between quantities by using points on a scatter plot. Represent data on two quantitative variables on a scatter plot, and describe how the variables are related. a. Fit a function to the data; use functions fitted to data to solve problems in the context of the data. Use given functions or choose a function suggested by the context. Emphasize linear, quadratic, and exponential models.

Typically used for a small set of values, a dot plot uses a dot for each unit of measurement. For the preceding undergraduate expense data, if we just wanted to compare the dollar values and were not concerned with the categories, a dot plot would look like that shown in Figure 1.
