Data Fitting with MATLAB - MATLAB & Simulink
Accessed Dec. Jerry forgot to plug in his laptop before he went to bed. What coordinate points represent the screenshots of the battery charge indicator? What scale will you use for your scatter plot? How will you determine the equation for your line? Will everyone in the class have the same equation?
Why or why not? This problem engages students in MP. Information is given in an unconventional way and students must determine what the variables are, how to represent the relationship between then visually, and then what conclusions they can make. Illustrative Mathematics Laptop Battery Charge.
Thanks for putting in the effort!

Include review problems for 8. Revisit the problems from Lesson 4 where students drew lines to data sets. Have students write the equations for their lines of fit. A task that represents the peak thinking of the lesson - mastery will indicate whether or not objective was achieved.

Use the scatter plot to answer the questions that follow. An example response to the Target Task at the level of detail expected of the students. Create scatter plots for data sets and make observations about the data. Informally fit a line to data. Judge the fit of the line and make predictions about the data based on the line.
Create and analyze two-way tables representing bivariate categorical data. Calculate relative frequencies in two-way tables to investigate associations in data.

You've summarized your result in a table. If there is, as in our first example above, no apparent relationship between x and y the paired data are said to have no correlation and x and y are said to be independent. From a scatter plot you can make predictions as to what will happen next.
To help with the predictions you can draw a line, called a best-fit line that passes close to most of the data points. Approximately half of the data points should be below the line and half of the points above the line. If the data points come close to the best-fit line then the correlation is said to be strong.
To find the most accurate best-fit line you have to use the process of linear regression. For this you have to use a computer or a graphing calculator. Enter the x and y -coordinates in your calculator and plot the points. The points seem to approach x -axis asymptotically. So, we assume an exponential model.
