Statistics Resources

Please keep in mind that any videos, calculators, and notes are no substitute for attending class. All the resources on this page are here to supplement the information from your instructor and textbook. First and foremost please be sure to follow any directions your teacher provides before using SSC resources to ensure you're meeting course requirements.


Check out this playlist full of videos demonstrating how to use different features of StatCrunch. Each video is short and to the point so you can easily work through your homework and practice problems. You can also find these videos and more under the "tech tutorial" tabs for each chapter where applicable;

CHAPTER 1

A brief overview of statistics and common vocabulary used.


Note: The narrator in the Simple Learning Pro videos uses the term "categorical data" but in your course you'll see the term "qualitative data". 

Learn about the Placebo Effect, Control Groups, and the Double-Blind Experiment


CHAPTER 2

This video shows how you can find your 3 quartiles, the IQR, and identify outliers using either StatCrunch or Excel.

This video demonstrates how to easily use StatCrunch to calculate mean, median, mode, and other common values.

This video demonstrates how to easily use Microsoft Excel to calculate mean, median, mode, and other common values.


Quickly learn about bar charts, pie charts, histograms, stem-and-leaf plots, and learn about which type of graphical tool is appropriate for describing quantitative variables, and qualitative variables.


 

Note 1: The narrator in the Simple Learning Pro videos uses the term "categorical data" but in your course you'll see the term "qualitative data".

Note 2: Please skip time index 1:47 to 2:43. This video does not cover class boundaries (learned in chapter 2.1) so please skip this small section of the video to avoid confusion.

This video quickly demonstrates how to find and compare the mean, the median, and the mode. You'll also cover how the shape or skew of a distribution affects each of them.


CHAPTER 3

Quickly calculate combinations in either StatCrunch or Microsoft Excel

Quickly calculate factorials or permutations in StatCrunch or Microsoft Excel

Quickly calculate permutations in either StatCrunch or Microsoft Excel


Note: Your course will not cover Exhaustive Events so you can stop watching this video at time index 2:09
Factorials overview

CHAPTER 4

Easily and quickly find the mean, variance, and standard deviation of a probability distribution in StatCrunch or Microsoft Excel.

CHAPTER 5

CHAPTER 6

Confidence intervals crash course by CrashCourse on YouTube.

All about confidence intervals and margin of error regarding proportions from Khan Academy

CHAPTER 7

QUICK NOTES:

Either hypothesis—the null hypothesis or the alternative hypothesis—may represent the original claim!

Regardless of whether you're making a statement about the mean or a proportion, regardless of which hypothesis is the claim, remember that the null hypothesis must contain a symbol of equality and the alternative hypothesis must complement it. Here are some examples of possible hypothesis pairs:

 

CHAPTER 9

Use StatCrunch to find the equation of a regression line and create a matching scatter plot

Use StatCrunch to find the correlation coefficient and create a scatter plot.

Note: For an example of making a prediction or forecast using your pre-calculated linear regression equation, skip to 7:25 and watch until 8:15. Also note that the presenter arbitrarily rounds the values of a and b. Be sure to round as indicated on your homework, quizzes, or tests.
