  4. Practice with TI-84  Finding correlation coefficient, r, And Regression Lines

  5. Outliers Before you were used to eye-balling for an outlier.  However, to technically be a true outlier, a data point must be one and one-half times the interquartile range. Formula for an Outlier:  

  6. EX1 The  data is the number of home runs scored over 18 seasons. Make a Box Plot on your calculator for the data. Is there an outlier?

  7. The following data is the number of home runs scored over 18 seasons. Make a Box Plot on your calculator for the data. Is there an outlier?

  10. What’s the difference in a histogram and a bar graph? https://www.youtube.com/watch?v=JsEwJD1mYpU

  11. Histograms A histogram is a bar graph that is used to display the frequency of data divided into equal intervals. The bars must be of equal width and should touch but not overlap. The heights of the bars indicate the frequency of data values within each interval.

  12. Histograms A histogram is a bar graph that is used to display the frequency of data divided into equal intervals. The bars must be of equal width and should touch but not overlap. The heights of the bars indicate the frequency of data values within each interval.

  13. Mean of Histograms
