SPSS made easy.
The videos on the channel were created to teach students how to conduct analyses on SPSS - quickly and easily. They also indicate how to report results in accordance to the guidelines of the American Psychological Association (APA).
They were created by David Robinson (BSc, MSc, PhD) who has tutored life science students since 2010.
The SPSS for Students guide (available in digital and paperback formats) is available on Amazon: amzn.eu/05fdkSo (digital), amzn.eu/8tiZgZQ (paperback). The guide covers t-tests, ANOVAs, ANCOVAs, MANOVAs, MANCOVAs, simple and multiple linear regression, chi-squared tests of independence, and Pearson correlations.It uses real-world examples that college/university students are able to relate to (e.g., how far can people walk after drinking tequila?) and demonstrates how to report results according to APA guidelines.

well explanatory Doc.
Thanks!
hi David, how would an item be removed if is needed
Hi, analyses based on questionnaire data usually require that you calculate sum or mean scores. I.e., rather than doing analyses on specific items, it's more common to do an analysis on a variable that you create by adding up all of the scores for the individual items or by finding the mean of the scores for the individual items. Therefore, if you needed to remove an item, you could just not include it when creating this variable.
The MSWord doc about how to report is very useful
Thanks David, this video was really helpful - definitely checking out your book! I ran a binary logistic regression with a categorical outcome variable (recovered or not recovered) and hours of treatment (ranging from 0-5). I have the odds ratios for each hour of treatment (e.g., 5.08 times more likely to recover after 1 hour of treatment, etc. for each hour). My question is, how would you suggest I best analyse the data if I wanted to see whether later hours of treatment (3-5 hours) were as important as the earlier hours (0-2)?
Hi Leon, glad you found the video helpful and I hope the book is too if you check it out! Perhaps you could create a new binary variable for hours (e.g., 0 = 0-2 and 1 = 3-5) and then run the analysis again to see whether it has a significant effect on recovery.
Very useful and comprehensive.
6:45 I have just learned that if you have a subcategory that is too small (in my case age group <40 yrs T2Ds represented 18 of 400), then it is better to use another group as a reference with a higher representation in the sample (in my case >60 yrs ).
If i can like this video more than once, i would definitely do. please could you make a brief video on how to interpret a categorical independent variable that contains three or more classes ; how to compare results of these classes to the chosen reference.
Thanks, I'll add that to my list!
@@DavidRobinsonPhD 🤩😍🤩
how to calculate this effect size with cohen's d?
Cohen's d is usually used with parametric tests (e.g., t-tests) rather than with non-parametric tests (e.g., the Wilcoxon test) as it's based on means, which may not be informative when data are not normally distributed.
This was perfect and exactly what I needed to complete my analysis in SPSS using a paired t-test! Instructions were so easy to follow. I LOVE that you included how to explain the results!!! So glad I found your video! Thank you!
Thanks, I'm glad it helped!
Wonderful explanation but i have annoying question if you don't mind Is the focus always on interpreting the odds of "Event To Occur" rather than the odds of "NOT" in logistic regression analysis? because i have watched a video where a person interpret the results as the odds of "not completing a course". So, How can i decide which one to interpret?
Hi, thanks for your question. Typically, we interpret the odds of the "event" occurring (like "completing a course") because that's often the behaviour or outcome of primary interest. However, you can interpret the odds of the opposite event (e.g., "not completing a course") if that aligns better with your research focus or if it's more meaningful for the context. The choice depends on which outcome provides clearer insights for your audience or is most relevant to your study. For example, if you're studying factors that contribute to course dropout rates, it might make more sense to interpret the odds of not completing the course. Conversely, if you're looking at predictors of successful completion, you’d focus on the odds of completing it.
@@DavidRobinsonPhD Thanks for prompt response, highly appreciated. I got it but is there any additional step on spss to make the result represent the likehood of "not"?
@@adlesal24 You could consider recoding your dependent variable (e.g., 0 becomes 1 and 1 becomes 0).
@@DavidRobinsonPhD thank you, i got it.
Thank you for the video. how about of the sig value is written as a dot (.) on one of group and what is lower bound of the trus significance? Is it consider normally distributed since the sig. Value is 0.200?
Thank you for watching the video and for your question! When SPSS shows a dot (.) in the "Sig." value, it usually means there’s insufficient data in that specific group to calculate the significance level, often due to a small sample size. This means the normality test for that group couldn’t be performed, so the result is indeterminate rather than a confirmed outcome. As for the lower bound of true significance, this can depend on the sample size and the test used. Generally, for tests of normality (like Shapiro-Wilk or Kolmogorov-Smirnov), a "Sig." (p-value) of 0.200 or greater suggests that the data do not significantly deviate from a normal distribution, indicating normality. So, yes, if a group has a significance value of 0.200 or higher, it’s usually considered approximately normally distributed.
Great
Thanks!
thank you. it was most comprehensive explanation that can be found.
