- A few of you need to take or finish your test on logarithmic functions. See me if you aren't sure when you're making that up.
- The grades were pretty good for the most part. You should be happy.
- And now for something completely different: STATISTICS.
Today (February 23 for 1A) and tomorrow (February 24 for 2B and 3B) we are learning about ONE-VARIABLE STATISTICS.
In this section, we learn how to find the MINIMUM, Q1, MEDIAN, Q3, MAXIMUM, MEAN, and STANDARD DEVIATION. Most of these you have seen before.
(1) First, we did the calculations by hand (you will NOT have to do this on the test):
(2) Then we had the calculator do the hard work, by using [STAT] [EDIT] [1] to put the data into L1 and [STAT] [CALC] [1] to get the SAME answers.
(3) We learned three different ways to plot our results: the DOT PLOT, the HISTOGRAM, and the BOX AND WHISKER PLOT.
(4) Then we practiced. Practice #4 is shown here. Please do Practice 1, 2, and 3 on your own. The answers are taped up on my board so you can check your work.
Next time, we will review this briefly before moving on.
