- Using a Harry Potter theme, I run an independent samples t-test to see if there is a gender difference (witch vs wizard) on OWL exam scores. This is just a quick independent samples t-test tutorial in SPSS 22 that hopefully will help you run the test and interpret the results. Independent samples t-tests are used when there are two groups to compare. For example, gender differences in some variable (e.g., math achievement). The type of question we could answer using an independent samples t-test in SPSS is: Is there a gender difference in math achievement on the SAT? For data, all you'd need is two columns of data in SPSS. Please note, in this case, I'm going to say that in our sample we have ONLY two genders - cismale and cisfemale. The first column would be sorted by gender (e.g., 0 = cismale; 1=cisfemale). The second column would be SAT Quant scores. That's all you need to run an independent samples t-test in SPSS. Also, note: In good, quality research it is highly important to check assumptions for the statistical tests being used--in this case, an independent samples t-test. I'll update this information at another time. You can quickly run an IS t-test in SPSS! Just follow the tutorial and you'll get results that are very easy to understand! :)
Hey everyone! This is just a quick video to help you run an independent samples t-test in SPSS. I've used my love of all things Harry Potter to put a spin here. Let me know if you like it! Please give this video a thumbs up and comment if it helped you or a thumbs down and comment if it didn't and you need more clarification. I'm always willing to help clarify information or make better videos attending to your needs! :)
Mam, this visual is not that much clarity
Merlin's beard!
If my stats lecturer was as awesome as you with the Harry Potter references I swear I would be top of the class. Thank you for your video! This is my second time around doing Research Methods and Statistics and SPSS and myself just have never mixed well. You've definitely helped, so, I thank you!
+The Catto I'm glad this helped! I can't hold back the Harry Potter references...ever. I thought it would be much more interesting than doing something with drug A vs. drug B or therapy A vs. therapy B. :)
WONDERFULLY EXPLAINED
Hey! Could you please explain how to know gender male or female got higher score?
Sorry, this comment was in the "held for review" section and I did not realize it. It honestly does not matter. You just have to assign a value (0 = Male, 1= Female) or (0= Female, 1= Male). Either way is perfectly acceptable. You just need to make sure you know which you have done. The easiest way to do this is use that format for all of your data sets. I find it the easiest to use 0-1 as Male-Female because that's naturally the way I mention them.
