What is your first step of finding the statistics of a data set if you are given a calculator. How will you "put dots into the calculator"?
First you must turn the set of dots into a set of numbers (the dots represent the amount of times that number appears in the data set). Then you will go to STAT- EDIT and eneter the values in L1 just like any other set of data
What are the parts of the box plot and what are they called all together?
1st line: minimum
2nd line: Q1
3rd line: median
4th line: Q3
5th line: maximum
These five together are called the 5-number summary.
What does the x̄ represent in the statistics list?
Mean

2 box plots summarize the ages of athletes on the swim team and the track team the five number summary represents the box plots of the two teams.
Swim Team: Track Team:
- min: 9 - min: 8
- Q1: 12 - Q1: 11
- med: 12 -med: 12
-Q3: 16 -Q3: 14
-max:17 -max:15
1) The IQR of the swim team is less than the median age of the track team.
2) There are more athletes on the swim team than on the track team.
3) The median age of both teams is the same.
4) The range of ages of the swim team is smaller than the range of ages of the track team.
3) The median age of both teams is the same.
What does the mode mean?
and
Where can you find it on the calculator?
The mode is the number that appears the most frequently. (MOde=MOst)
Trick question: You cannot find it on the calculator, you have to find the number that repeats the most times.
If you are given an equation in y= form, what are your steps to graph it?
