Lesson 230 of 1524
3.5 Using the Correlation Coefficient
You thought about whether there would be a strong correlation or not as well as whether the relationship was a positive or negative correlation
Practice this chapterYou thought about whether there would be a strong correlation or not as well as whether the relationship was a positive or negative correlation In addition, you interpreted the coefficients of the equation of the line of best fit and used the equation to make predictions
You examined a pair of variables and a correlation coefficient to describe the relationship between the variables as strong or weak and as positive or negative
Be able to describe the strength of a relationship between two variables; use technology to find the correlation coefficient and explain what the value tells me about a linear model in everyday language; calculate the correlation coefficient for cricket-chirp data in the table below.
