Exploring our data about burnout and job satisfaction, we predict an outcome with a single variable using simple linear regression in JASP. I explain how regression works, then open an SPSS dataset in JASP. We explore the assumptions of homoscedasticity and linearity with a scatterplot and normality using a Shapiro-Wilk test. Later we examine the residual statistics for outliers and use the Durbin-Watson test to check for independence of observations. Assumptions met, we conduct the simple linear regression in JASP, interpret the results, and write up the findings in APA style.
I also answer the question: “What is the difference between capital R and lower case r, for reporting?”

This video teaches the following commands and techniques in JASP:
Importing a .SAV into JASP
Simple Linear Regression
Assumptions for regression
Interpreting regression coefficients
Using a regression equation for prediction
This video uses the dataset Job Satisfaction.SAV and JASP version 12.0

These videos are amazing! If you ever have time to do a multiple linear regression in JASP, I will forever be in your debt!!

Multiple regression is on the way. I am working on an extensive series of videos on Excel and JASP, including several variations on regression. Hope to add some logistic regression, Cox regression (survival analysis), and hierarchical regression, too.

Great vídeo! I have a question (from a non statistician): What can we do if the Durbin-Watson statistic does not fall between 1 and 3, what are my options as researcher? Should I drop my attempt to do a regression? Thanks a lot

I have had several requests on logistic regression. Plan to have something either later this semester.There is an excellent course on Course called "Logistic Regression in R for Public Health" that I recommend.

why did you choose the durbin-watson value of H1 and not H0?

Please tell all the other professors in your uni to do p values on linear regression...we do linear regression ALL the time in bio, physics, chem, and its easy to throw up a graph in excel and get the equation etc etc and find the relationships etc etc but it wasn't until I undertook my own personal research project and started wanting to find a way to run stats on a line that looks like there is no significant change on the dependent variable over a range of concentrations of a toxin, that I finally wondered if there was a way to determine this rather than running anova at each concentration of a dose response line and I am still probably doing it wrong, but I learned something.

hi, would you mind to give an explanation on how to use Weighted Least Squares in Linear Regression on JASP?

Good question and I don't have an answer off the top of my head. I will look into it. Great suggestion.

These videos are amazing! I am being asked to find the linear correlation coefficient between the two variables. What number do I look for in JASP. to report that number? I assume I use the Regression Linear Regression, right? Is the the H1 unstandardized?
@ResearchByDesign
@ResearchByDesign Год назад
If you are examining only two variables, then the r correlation coefficient will be exactly the same as the b regression coefficient. If you have multiple predictors in your regression model, then b will be unique to each predictor. The standardized regression coefficient is r, the unstandardized is in terms of the variable being measured. Hope that helps

@eddikalmanczhelyi7140 3 года назад
isn't the formula, Y = a + b * X ?
@xitslaura_5712
@xitslaura_5712 3 года назад
for the equation, did you minus bx because your b was a negative answer? my b is positive so does that mean I should add bx?
@ResearchByDesign
@ResearchByDesign 3 года назад
Correct...the formula is bx+a, but in my case the b was negative, making it subtraction. Your b is positive, so it will be addition.

Yes, eventually...I am teaching a class this fall that will cover various forms of regression and I will be adding new videos for each one of them. It is not going to be right away, however.

Is there a way to find beta, or the probability of a Type 2 error with this test? What can I do to find it? Awesome explanation, by the way!
@ResearchByDesign
@ResearchByDesign 3 года назад
Good question...the Type 2 error would only relate to the ANOVA testing whether the entire model (or additions to the model) are significant. You could also examine the confidence intervals. Assuming that you have a large sample size, which is kind of necessary to run a regression in the first place, power should not be an issue. That said, I don't know of a specific test. Best!
