1 Scatter Plots Scatter 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.

2 Scatter Plots Scatter 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 Cost of Party ($)

3 Scatter Plots Scatter 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 Cost of Party ($) Create a coordinate grid

4 Scatter Plots Scatter 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 Cost of Party ($) Create a coordinate grid 2.Number and label each axis Number of Guests Cost of Party ( $ )

5 Scatter Plots Scatter 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 Cost of Party ($) Create a coordinate grid 2.Number and label each axis 3.Plot each data value Number of Guests Cost of Party ( $ ) ( you might have to estimate the location of the point )

Example : Create a scatter plot for the following table : Number of Guests Cost of Party ($) Create a coordinate grid 2.Number and label each axis 3.Plot each data value Number of Guests Cost of Party ( $ ) ( you might have to estimate the location of the point )

12 Scatter Plots Scatter 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 # 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 ? Hours Worked Tips earned ( $ ) 120

13 Scatter Plots Scatter 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 # 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 ? Hours Worked Tips earned ( $ ) 120 From the scatter plot, we can see that the last 8 hour shift she worked she earned $70 in tips…

Example # 2 : During the month of June, Sarah created a scatter plot that showed the hours worked and how much she earned in tips Hours Worked Tips earned ( $ ) 120 Sometimes we will need to extrapolate the graph. That is, estimate the data past the known information.

15 Scatter Plots Scatter 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 # 2 : During the month of June, Sarah created a scatter plot that showed the hours worked and how much she earned in tips Hours Worked Tips earned ( $ ) 120 Sometimes we will need to extrapolate the graph. That is, estimate the data past the known information. This is called a “line of best fit”.

16 Scatter Plots Scatter 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 # 2 : During the month of June, Sarah created a scatter plot that showed the hours worked and how much she earned in tips Hours Worked Tips earned ( $ ) 120 Sometimes we will need to extrapolate the graph. That is, estimate the data past the known information. This is called a “line of best fit”. This line “fits” in between the data points and extends beyond our last data item…

Example # 2 : During the month of June, Sarah created a scatter plot that showed the hours worked and how much she earned in tips Hours Worked Tips earned ( $ ) 120 Using this “line of best fit”, we could estimate what Sarah would earn if she worked a shift that hasn’t been plotted…

Example # 2 : During the month of June, Sarah created a scatter plot that showed the hours worked and how much she earned in tips Hours Worked Tips earned ( $ ) 120 Using this “line of best fit”, we could estimate what Sarah would earn if she worked a shift that hasn’t been plotted… For example, how much could Sarah expect earn if she works a 12 hour shift ?

About $95.00
