Once all data are collected, checked
and posted, students will organize and describe data.
for Core Curriculum Standards.
Grades 9 and up may also include:
Students will organize and describe collected data.
Students will construct, read, and interpret tables and graphs.
Students will make inferences and convincing arguments that are based on
Students may evaluate arguments that are based on data analysis.
Students will conduct an experiment and interpret and communicate outcomes.
Students will construct and draw inferences from tables and graphs that
summarize data from real-world situations.
Students will use correlation coefficient to predict from data.
Students will understand and apply measures of correlation.
Students will understand a sampling and recognize its role in statistical
Using checked data, students will begin
graphing in preparation for analysis and final report.
Have students make a table whereby the first column represents the school
name, the second column represents the school's distance from the nearest
power plant, and the third column represents the pH levels. All schools
should be included in this table.
Students will make a scatter plot whereby the horizontal axis represents
the distance and the vertical axis represents the pH level.
Students will plot the data from their table and look for a trend in the
data. (Click HERE for pre-lesson plan.)
If a correlation exists, students will draw a line of best fit.
Have students discuss analysis and prepare FINAL
* For higher level students (with Statistics background):
If a correlation exists, have students determine the correlation coefficient
to measure the extent of the relationship.
Compute and graph the regression line.
Find estimates of the dependent variable (pH) for a given value of the
independent variable (distance).
