Dealing with Data Online Study Group

Things you will need to know for the test:

• Finding Measures of Center/Measures of Central Tendency (Mean, Median, Mode)
• Choosing the Best Measure of Center (Mean, Median, or Mode)
• Finding and Describing Measures of Variation (Range, Interquartile Range) You will only be asked to describe the MAD, not calculate it.
• Finding a 5 point summary to create a Box-and-Whisker Plot
• Analyzing and describing the uses of data displays (specifically Box-and-Whisker Plots, Histograms, and Dot Plots)
• Drawing conclusions from the data you collected.
• Statistical vs. Non-Statistical Data
• Choosing the Best Data Display

Use the comment section below to ask questions or respond to questions asked by a classmate.  I will be checking the comment section at 8:30 this evening to answer questions as well.

Helpful Study Tips:

• Look over/correct Quizzes
• Re-watch videos from this unit. (They can all be found here.) ONLY WATCH the videos you feel you need to review.  DO NOT WATCH ALL OF THE VIDEOS AGAIN!!
• Look over your WSQs and Notes we took as a class (especially your foldable on Mean, Median, and Mode in your comp. book).
• Check over you study guides again.
• Try out some of the problems on the Minute to Win It review game posted on Bb.
• Participate in the Online Group discussion in the comment section below.
• Ask Mrs. Sopko if you have any further questions in the comments section below.

Test Structure:

• There are no multiple choice questions on the test.  
• The tests are set up very similar to the quizzes.  You will have to compute some answers and you will need to explain some of your answers.
