  6. Scatter Plots and Lines of Best Fit Day 1 - Correlations

  7. Scatter Plots and Lines of Best Fit I can: • identify the correlation of a scatter plot.

  8. Describe this graph in a sentence. Review from 7th Grade:

  9. As the temperatures increase, the sales increase. Review from 7th Grade:

  10. What type of “sales” might this be representing? Review from 7th Grade:

  11. Sales might represent ice cream, snowballs, bathing suits, fans, air conditioners, etc. Review from 7th Grade:

  12. Scatter Plots and Lines of Best Fit Scatter Plot: A scatter plot is a graph of plotted points that shows a relationship between two sets of data.

  18. Notes - Scatter Plots and Lines of Best Fit A perfect correlation is a straight line.

  23. Notes - Scatter Plots and Lines of Best Fit

  24. The data shows no relationship. Notes - Scatter Plots and Lines of Best Fit

  25. Write this definition in your spiral!!! Notes - Scatter Plots and Lines of Best Fit

  26. Write this definition in your spiral!!! Notes - Scatter Plots and Lines of Best Fit

  27. Notes - Scatter Plots and Lines of Best Fit

  28. Write this definition in your spiral!!! We will use technology to calculate the correlation coefficient. Notes - Scatter Plots and Lines of Best Fit

  29. Negative Correlations

  30. Perfect Negative Correlation The lowest possible correlation value is -1. This occurs when the data has a negative association and the points are in a straight line.

  31. Strong Negative Correlation This occurs when the data has a negative association and the points are generally gathered close to a line.

  32. Weak Negative Correlation This occurs when the data has a negative association and the points are not generally gathered close to a line.

  33. exactly -1 closer to -1 farther from -1

  34. Positive Correlations

  35. Weak Positive Correlation This occurs when the data has a positive association and the points are not generally gathered close to a line.

  36. Strong Positive Correlation This occurs when the data has a positive association and the points are generally gathered close to a line.

  37. Perfect Positive Correlation The highest possible correlation value is +1. This occurs when the data has a positive association and the points are in a straight line.

  38. closer to +1 exactly +1 farther from +1

  39. No Correlation

  40. No Correlation This occurs when the data has neither a positive nor a negative correlation. The correlation coefficient will be zero.
