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...

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...

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...

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.

A worksheet on correlating conjunctions could be used as either a check for comprehension or as a homework assignment. Whether or not conjunctions are their thing, the activity will not only engage young grammarians, but also teach them...

Stop ... grammar time! Pupils complete worksheets to practice using the correct verb tense and identify correlative conjunctions. Next, scholars apply their new grammar skills to edit their draft opinion speeches.

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 Renaissance is the theme of a five-week unit designed to boost reading comprehension, spelling, vocabulary, and expository writing skills. Scholars listen to and discuss daily readings and engage in skills practice activities...

Is there a correlation between the number of cats you own and your age? Use a scatter plot to analyze these correlation questions. Learners plot data and look for positive, negative, or no correlation, then create stem-and-leaf plots to...

Statistics come front and center in this unit all about analyzing discrete data. Real-world situations yield data sets that the class then uses to tease out connections and conclusions. Beginning with the basic histogram and...

Mortgages, payments, and wages correlate with each other. The short assessment presents scatter plots for young mathematicians to interpret. Class members interpret the scatter plots of price versus payment and wage versus payment for...

Make an estimate by getting in line. The class works with scatter plots and lines of best fit to make an estimate for given values. Pupils determine whether there is a positive or negative correlation and draw a best-fit line. Using the...

Given the price of crude oil, gasoline, and diesel for the past several years, pupils plot the data to determine whether a correlation exists. Learners determine a regression line and predict the price of gasoline and diesel in the...

Scatter plots tell a story about the data — you just need to be able to read it! Building from the previous lesson in the series where learners created scatter plots, they now learn how to find associations in those scatter plots....

Forgive me, I regress. Building upon previous modeling activities, the class examines models using the regression function on a graphing calculator. They use the modeling process to interpret the context and to make predictions...

Creating a definition may be easier than it sounds! Give your classes experience creating their own definition. Scholars examine the meaning of the compact-ness of a scatter plot and create their own definitions based on measurements. 

What is the difference between money and bartering, and how is money valued when considering inflation? Delve into the correlation between these fundamental components of economics with this detailed resource, which consists of...

You may be able to see patterns visually, but mathematics quantifies them. Here learners find correlation in scatterplots and write equations to represent that relationship. They fit a line to the data, find two points on the line, and...

There is a strong correlation between the carbon dioxide concentration in the air temperature. Scholars offer explanations for the correlation in one of four AP® free-response assessment questions. Their analyses in the other questions...

There are many ways to correlate coffee to life, but in this case a worksheet looks at the price of two different sizes of coffee. It requires interpreting a graph with two unknown variables, in this case the price, and solving for...

An inquiry-based algebra lesson explores real-world applications of linear functions. Scholars investigate four different situations that can be modeled by linear functions, identifying the rate of change, as well as the...

There are a lot of myths surrounding marijuana. Read a passage that clarifies the dangers of teens smoking marijuana, its harmful effects on the development of the brain, and the possible correlation of cigarette smoking to marijuana...

What mental health conditions could affect a student's performance while auditioning for a play? How do stress levels correlate with student absences? Scholars examine case studies to learn more about the mind and mental health or to...

Scholars keep meteors from hitting their alien's spaceship by choosing the multiplication problem that correlates to the number displayed.
