The Student Success Commons at York County Community College: MAT 124: Statistics

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

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.

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

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

Quickly and easily find areas when information about z-score(s) is known using StatCrunch.

Confidence intervals crash course by CrashCourse on YouTube.

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

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.
