Scatter PlotsScatter plots are used when you want to represent

data from a table. Match the data values in the table to the coordinates of the points on the scatter plot.

Scatter PlotsScatter plots are used when you want to represent

data from a table. Match the data values in the table to the coordinates of the points on the scatter plot.

Example : Create a scatter plot for the following table :

Number of Guests 4 14 6 21 20 12

Cost of Party ($) 65 170 92 230 190 130

Example # 2 : During the month of June, Sarah created a scatter plot that showed the hours worked and how much she earned in tips.

If Sarah is working an 8 hour shift tonight, how much can she expect to earn in tips according to her scatter plot ?
