| Title: Collecting & Analyzing Data using TI-83 calculators |
Audience: Students
Days/Times:
Group A: 7:00 p– 8:15 pm on Monday
8:30 – 11:45 am on Thursday
Group B: 7:00 p– 8:15 pm on Tuesday
1:15 – 4:30 pm on Thursday
Lead Faculty: Mrs. Lisa King &/or Mrs. Carol Kuhlman
Objectives with Brief Description of Content:
Students/Teachers will
1. collect or obtain data from various experiments.
2. enter data in the LIST on the TI- 83 calculator.
3. discuss different statistical information that can be useful when analyzing data.
4. use calculator operations to obtain statistics (summation [Sx], mean [x], median [Q2], mode(s), range [max-min], quartiles [Q1, Q3], standard deviations [Sx or sx]) for data in LIST.
5. graph data from the LIST using
· box & whiskers.
· histograms.
· x-y plots. (simple regressions)
6. discuss and analyze the graphical representation of data.
7. discuss independent variables (IV), dependent variables (DV), and
controlled variables for the various experiments. Look at
the relationship of variables and determine if they are directly or
indirectly related.
8. watch a demonstration of calculating the slope of a line manually.
Discuss the significance of the line’s slope and y-intercept and
then use these values to determine the linear equation.
9. use the calculator’s linear functions and obtain slope (m or a),
y-intercept, and Pearson’s r-correlation for a linear regression.
Materials and Handouts will be given out for the following
