12.1c - Statistical Inference for LSRL's (Part 2)
In this video, we continue our discussion on confidence intervals for the slope for a LSRL. We also learn how to conduct a significance test on our slope as well!

12.1b - Statistical Inference for LSRL's (Part 1)
Переглядів 1963 роки тому
In this video, we discuss the rationale for doing inference on LSRL problems. Then, we learn how to construct a confidence interval for the slope of a LSRL.
12.1a - Review of Linear Regression
Переглядів 2423 роки тому
Our final chapter covers statistical inference on Linear Regression. In order to understand this concept, we must first review the Least Squares Regression Line information we learned in Chapter 3!
11.2c - Chi Square Test for Independence
Переглядів 2163 роки тому
The Chi Square Test for Independence works a LOT like the Chi Square Test for Homogeneity. Here, we will learn the difference between the two tests, and decide when each method is appropriate.
11.2b - Chi Square Test for Homogeneity
Переглядів 2693 роки тому
Here, we learn calculator commands and the full 4 step process for a Chi Square Test for Homogeneity, which is typically used in experiments involving two categorical variables
11.2a - Chi Square Two Way Tables
Переглядів 2473 роки тому
In this video, we learn how to prepare two way tables for Chi Square analysis. We review conditional distributions, and then build the pieces necessary for a Chi Square Test for Homogeneity
11.1b - More on the Chi Square Goodness of Fit Test
Переглядів 2733 роки тому
In this video, I cover the "4 step process" for answering free response questions related to the Chi Square GoF Test. I also show calculator commands that can be used to answer these questions.
11.1a - Chi Square Goodness of Fit
Переглядів 3013 роки тому
Formalizes the concepts we investigated in the previous video. We will learn how to calculate a test statistic for a Chi Square Goodness of Fit test, and we will learn how to turn that statistic into a p-value using a table.
11.0 - Chi Square Investigation
Переглядів 4503 роки тому
Through the classic M&M problem, we will investigate and develop the concept of a Chi Square test statistic for analyzing a categorical variable with more than 2 possible values.
10.2b - Significance Tests for a Difference in Means
Переглядів 2463 роки тому
How to conduct a significance test on the difference between two means.
10.2a - Confidence Intervals for a Difference in Two Means
Переглядів 2673 роки тому
How to construct and interpret a confidence interval for the difference in two means. I do show where the necessary formulas come from, but we will largely use the calculator to generate our intervals with 2 parameters.
10.1b - Significance Tests for a Difference in Two Proportions
Переглядів 2893 роки тому
In this video, we apply our knowledge of significance testing to problems where we wish to compare two proportions
10.1a - Confidence Intervals for a Difference in Two Proportions
Переглядів 4353 роки тому
In Chapter 10, we learn how to handle a comparison between two different groups. This is an incredibly common occurrence - in just about any experiment, you will want to compare your treatment groups' results to each other. This video specifically develops the sampling distribution for the difference in two proportions, and uses it to construct confidence intervals on that difference.
