Please keep in mind that any notes, videos, and calculators provided on this page are no substitute for attending class. These resources are here to supplement the information from your instructor and textbook. First and foremost please be sure to follow any directions and use any resources your teacher provides.
Many statistical calculations call for these symbols, so to avoid feeling overwhelmed when faced with a formula, print out and keep this glossary handy!
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;
Any YCCC student enrolled in a math (MAT) class or taking a course that involves math—yes, even if it’s just entering a crazy formula in Microsoft Excel!
Math tutoring covers any MAT course as well as support for any student using Microsoft Excel to perform calculations. Tutoring for dosage calculations is also available with Karissa Cole.
Please note: classes coded as ACC, BUS, and FIN are not specifically covered under Student Success Commons math tutoring. Math tutors will help the best we can, but if you need support with any of these classes please reach out to your instructor and student success coach.
Our tutoring schedule is always available on our tutoring page. If you have additional questions about how and when you can get math support, please email Karissa.
Not at all! Tutoring is for everyone—whether you're trying to catch up, keep up, or level up.
Math tutoring at the SSC is walk-in friendly—just stop by during our open hours and a tutor will be happy to help you. You don’t need an appointment! Whether you can only stay for 10 minutes, or 4 hours, drop-in tutoring is here to fit your schedule.
Drop-in tutoring isn’t the same as a study group or a class. You’re welcome to work with friends, but it’s not required. Tutoring takes place in an open space, but your tutor will always give you one-on-one attention.
Tutors won’t lead a session like a teacher would. Instead, they’ll work with you on whatever concepts you need help with—at your pace and level. Since drop-in tutoring is student-driven, be sure to bring questions or topics you’d like to go over!
If you can't make it in person, you can also email us with questions or to connect with a tutor. And don’t forget—our website has a collection of helpful online resources, including videos, guides, and practice tools you can use anytime.
Your tutor will answer any questions, explain tricky concepts, help with practice problems, review assignments, and build your confidence. You won’t just get answers—you’ll learn how to find them.
Yes! While they won’t do your work for you, tutors can walk you through similar problems and show you strategies to tackle questions on your own.
That’s exactly why we’re here. Our tutors create a judgment-free zone where questions are always welcome, and mistakes are part of the process.
Take a deep breath—the Student Success Commons is here to help! Whether you're stuck on a math problem, stressed about a class, or just feeling overwhelmed, you don’t have to figure it all out on your own. Please email the SSC. Please include any information you think will help, such as your class and concerns, to ensure you're connected with the right resource for you.
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.
This document explains the differences between permutations, combinations, and factorials. It includes a handy flowchart to help you determine which one to use when, as well as several examples.
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:
This example problem shows how to find the correlation coefficient and linear regression equation, use the equation to make a prediction, and perform a hypothesis test on the correlation coefficient.
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.
