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...

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...

Introduce the concept of a correlation coefficient using an interactive lesson. Learners begin by manipulating a correlation coefficient and watching a graph change to represent the new value. Questions help strengthen their...

Help scholars explain the concept of positive and negative numbers. Here you will find three separate activities that will help them to correlate positive and negative numbers with real life. Note: Activities require that the teacher...

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...

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

High schoolers investigate different types of correlation in this statistics lesson. They identify positive, negative and no correlation as it relates to their data. They then find the line of best fit for the plotted data.

Seventh graders solve problems involving addition of positive and accentuating negative integers. In this adding real numbers lesson plan, 7th graders draw a number line on chart paper, complete a working sheet and use the Learning Gizmo...

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...

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....

In this graphing calculator worksheet for the TI-83 calculator, middle schoolers first observe a demonstration for calculating negative numbers. Next, students use their graphing calculator to answer 6 thoughtful T/F and short answer...

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...

Do big bodies make big brains? Let your learners decide whether there is an association between body weight and brain weight by putting the data from different animals into a scatterplot. They can remove any outliers and then make a line...

In this math worksheet, students identify the type (if any) of correlation on 6 scatter plots. They use information given on a table to create a scatter plot and identify the type of correlation. Students use the scatter plot to make...

In this scatter plots and line of best fit worksheet, students create scatter plots from given sets of data. They answer questions concerning the scatter plot. Students write the equation of a line, identify the type of correlation...

In this negative numbers worksheet, students use the TI-83 calculator to compare the value of negative numbers. Students explain in short answer format how they used the calculator to determine their answers.

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...

Scatter plots are a fun way to gather and collect relevant data. The presentation goes through several examples and then describes the different types of correlation. 

Learners investigate different correlations. In this algebra instructional activity, students analyze graphs and identify the lines as having positive, negative or no correlation. They calculate the line of best fit using a scatter plot.

In this scatterplots worksheet, 9th graders solve 18 different types of problems related to scatterplots. First, they represent a two numerical variable on a scatterplot and describe how the data points are distributed. Then, students...

Class members investigate relationships between two variables in the seventh installment of a 16-part module that teaches scholars how to find and describe patterns in scatter plots. Young mathematicians consider linear/nonlinear...

For this statistics worksheet, 11th graders analyze different scatter plot graphs for positive, negative and no correlation. They graph their data and analyze it using scatter plots.There is 1 question with an answer key.

Students examine the concept of scatter plots. They compare baseball statistics to locate the ones that correlate with winning, and identify the positive, negative, and no correlation in sets of data using MS Excel.
