Day 6: Analysis of the Rainfall of Tropical Storm Allison Continued Objectives: 1. Analyze
and organize data from a bar graph into a spreadsheet. 2.
Create a scatterplot graph of the data. 3.
Graph a trendline and determine a regression equation for the data. 4. Evaluate the accuracy of the regression equation to model the data. 4.
Interpret the results by doing each of the following:
a. Describe the situation (what the data means)
b. Identify the function, if the relationship does exist and write
it in functional notation.
c. Describe the transformations of the parent function.
d. Identify domain and range.
e. Identify the independent and dependent variables.
f. Evaluate the accuracy of the regression equation. g. Apply the results to the situation. Ab1A, b2C, c1B, b1A and b1B; included on TAKS Materials: 1.
Computer Lab with
Internet access and a word processing program. 2. Excel program with the Data Analysis Tool installed. (This comes with the program, but it is not loaded in a typical installation. It is on the Microsoft Office CD as an Add-In Tool and must be loaded into the program in order to do this assignment.)
3. Projection device
for displaying PowerPoint Presentation Activity: 1.
Using the PowerPoint presentation, Analysis
of the Rainfall of Tropical Storm Allison, the teacher will guide
the students through the situation/problem, explaining how to create a
spreadsheet from the data, how to create a graph, how to draw a trendline,
and how to write a regression equation. 2.
Using the graph in the presentation, the teacher will review
the concepts of identifying the type of function, functional notation,
independent variable, dependent variable, domain, range and
transformations of parent functions. 3.
Using selected slides from the PowerPoint handout, the
students will take notes and complete the assignment.
