*You do not have to do any problems by hand. You can use a calculator for each.*
Also, remember your chapter 3 take home quiz is due Monday! There is no other weekend homework--just come back ready to work! (The onslaught of quizzes is coming....)
Someone asked for this via email, so check it out: steps for a boxplot:
Here are the stops to draw a boxplot:
1. Use your graphing calculator to find the 5 number summary (enter your data in L1, then press Stat-->Calc-->1 Var Stats)
2. Plot Q1, Median, and Q3 with a vertical line--these create the box in our boxplot.
3. Calculate the fences (these are the cutoff points for outliers) with the following formulas: Q1 - 1.5IQR and Q3 + 1.5IQR
4. Plot any outliers (values that fall outside these fences) with a dot.
5. Draw the arms (or whiskers) of your boxplot to the highest and lowest data values within the fences. **Students often mess up this step and draw the arms to the fence values--these are not part of our data, so this is incorrect**
