Middle and high schoolers use a spreadsheet to graph data. In this graphing instructional activity, learners determine how two parameters are correlated. They create a scatter plot graph using a computer spreadsheet.

Is 0.56 stronger than -0.78? Interpret the correlation coefficient as the strength and direction of a linear relationship between two variables. An algebra lesson introduces the correlation coefficient by estimating and then...

Collect a variety of bivariate data. Groups determine sets of data that would provide a positive, negative, and no correlation. Team members gather their data through out the week. Scholars plot the data and determine the relationship...

Computers are useful for more than just surfing the Internet. Pupils first investigate scatter plots and estimate correlation coefficients. Next, they use Microsoft Excel to create scatter plots and determine correlation...

Determine how close the line is to the scatter plot. Clear video instruction shows how to plot a scatter plot and find the best fit line using the linear regression function on a calculator. Pupils use the information from the calculator...

Seeing is believing. Given several bivariate data sets, learners make scatter plots using the online SeeIt program to visualize the correlation. To get a more complete picture of the topic, they research their own data set and perform an...

Do women with college degrees get married later? Using a provided scatter plot of the percentage of women who earn bachelor's degrees and the median age at which women first get married over time, pupils conduct a linear regression...

Does the number of calories you eat affect the total time you sleep? Young mathematicians tackle this question by collecting their own data and making comparisons between others in the class through building scatter plots and regression...

Of course, there might be a correlation! Young mathematicians investigate several different data sets, create scatter plots, and determine any correlation. They consider whether a causation exists between any of the variables in question.

Check for understanding at the end of your descriptive statistics unit with an end-of-module assessment. It uses five questions to measure progress toward mastery of descriptive statistics standards. Each question is developed...

Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...

For this correlation and linear regression worksheet, students examine data to determine the statistic mean.  They compute the percent of the variability.  This three-page worksheet contains 16 problems.  Answers...

How good is the fit? Using an interactive, classmates create a scatter plot of bivariate data and fit their own lines of best fit. The applet allows pupils to display the regression line along with the correlation coefficient. As a final...

The data says it's a wrap. Pupils work through four review questions with multiple parts dealing with bivariate data. Questions cover creating and interpreting two-way tables and scatter plots with lines of best fit. Scholars finish up...

Dressing for success is not always about looking sharp. Sometimes it is about staying warm and dry. Present your class with an activity that challenges groups of pupils to design a layered material for blizzard conditions. The teams test...

Students explore the concepts of graphs, correlations, line of best fit, and the dipstick problem. In this graph, correlation, line of best fit and dipstick problem lesson, students solve problems on the above mentioned topics. ...

Finally! Math and Instagram have come together to discuss the correlation between likes and followers. High schoolers can't help but want to discover what makes one account more popular than another by developing a line of best fit and...

Seventh graders graph ordered pairs on a coordinate plane. They create a scatterplot. Additionally, they determine the line of best fit and investigate the slope of the line. Multiple resources are provided. An excellent resource!

Genetic analysis has gone to the dogs! Learners use real DNA information collected from dog saliva to study the relationship between genotypes and phenotypes. They analyze alleles to determine correlations to coat color, length, and...

Students investigate correlations between human body height and other human features. They select ten subjects and record each subject's age and gender and measure for height, wingspan, distance, and size of hands. After measuring, they...

Students investigate the differences between linear and exponential models.  In this linear and exponential models lesson, students make a table of given data.  Students determine if the data is linear or exponential by...

In this scatterplots learning exercise, students look at 4 graphs and determine the correlation between the data. Students then review 8 scenarios and decided the type of correlation.

Do homework grades really determine test scores? Learn whether lines of best fit, correlation coefficients, and residuals can be used to determine test scores when given homework grades. (It would certainly save teachers time in grading...

The higher the number of letters in the final word for the National Spelling Bee, the higher the number of people killed by venomous spiders. Obviously, those two facts correlate, but no causation exists. Scholars view data based on...
