Chi-Square Tests: Crash Course Statistics #29
Today we're going to talk about Chi-Square Tests - which allow us to measure differences in strictly categorical data like hair color, dog breed, or academic degree. We'll cover the three main Chi-Square tests: goodness of fit test, test of independence, and test of homogeneity. And explain how we can use each of these tests to make comparisons.

Data Science & Statistics: Chi-Squared Distribution
👉🏻 Sign up for Our Complete Data Science Training with 57% OFF: https://bit.ly/3hAy2GN
In this tutorial, we’ll talk about the Chi-Squared Distribution and its characteristics.
For starters, we define a denote a Chi-Squared distribution with the capital Greek letter Chi, squared followed by a parameter “k” depicting the degrees of freedom. Therefore, we read the following as “Variable “Y” follows a Chi-Square distribution with 3 degrees of freedom”.
Very few events in real life follow such a distribution. In fact, Chi-Squared is mostly featured in statistical analysis when doing hypothesis testing and computing confidence intervals. In particular, we most commonly find it when determining the goodness of fit of categorical values. That is why any example we can give you would feel extre...

Chi-Square Test [Simply explained]
The chi-square test is a hypothesis test used for categorical variables with nominal or ordinal measurement scale. The chi-square test checks whether the frequencies occurring in the sample differ significantly from the frequencies one would expect. Thus, the observed frequencies are compared with the expected frequencies in the Chi2-Test and their deviations are examined.

Probability and statistics on Khan Academy: We dare you to go through a day in which you never consider or use probability. Did you check the weather forecast? Busted! Did you decide to go through the drive through lane vs walk in? Busted again! We are constantly creating hypotheses, making predictions, testing, and analyzing. Our lives are full of probabilities! Statistics is related to probability because much of the data we use when determining probable outcomes comes from our understanding of statistics. In these tutorials, we will cover a range of topics, some which include: independent events, dependent probability, combinatorics, hypothesis testing, descriptive statistics, random variables, probability distributions, regression, and inferential statistics. So buckle up and hop on for a wild ride. We bet you're going to be challenged AND love it!
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.
