Tuesday, Wednesay, Thursday HW....

Tonight please use the ogive to determine the 5 number summary; then, use this five number summary to create a boxplot of heights!

  • For this ogive the max and min are not the xmin and xmax on the xaxis (like they were in class)--pay attention to detail!
  • Feel free to send me a Remind message to check your 5 number summary if you like...
  • When you go to create the boxplot be sure to calculate the fences! (no fence work = not full credit for hw)
    • If the max is an outlier you will not be able to draw the "upper arm" (because we don't know the highest data value that's not an outlier)
    • Similarly, if the min is an outlier you will not be able to draw the "lower arm" (because we don't know the smallest data value that's not an outlier)
    • If there are no outliers then we can draw both arms!
    • So your boxplot may show no arms, on arm, or both arms tonight--it all depends on those fences!
Due Friday: Chapter 5 Take Home Quiz!
  • The quiz provided today in class is due Friday--use your notes to get an A!
  • Technically I'm considering this take home quiz Wednesday's homework and Thursday's homework, but feel free to get a head start...
  • We will still have our chapter 5 vocab quiz in class on Thursday! Here's what's on it:
    • Range
    • Interquartile Range (IQR)
    • Standard Deviation (Sx)
    • Histogram (Definition: a graphical display that shows frequencies or counts of data for a given interval or for a given value)
    • Ogive
    • Boxplot
    • Stemplot
    • Mean
    • Median
    • Percentile
    • Appropriate summary statistics (for skewed vs. symmetric data)
    • Measures of center
    • Measures of spread
    • Center (from ch. 4 quiz)
    • Spread/Variability (from ch. 4 quiz)
    • Q1, Q3 (know their percentiles)
Tomorrow in class we'll start with a multiple choice pop quiz (yay)! Then we'll get into groups and work on a matching assignment, followed by some more "comparing boxplots" practice! See you there! Oh, and if you want to prepare yourself for this pop quiz (no longer pop...), be sure to review the following:
  • Know how mean and median are affected by skewness (or not affected), and why
  • Know the "appropriate summary statistics" based on shape
  • Look over the boxplot MC question we had as our warmup on Friday; we'll see another boxplot-based MC tomorrow
  • And then there's a surprise question or two...see you tomorrow! :)

Oh, and check out this video on mean absolute deviation!
