 So let's take an example and run the repeated mayor T test in SPSS. Here is an example. A researcher wants to examine the effect of our treatment on depression by meeting a group of eight people, eight participants before and after they receive a treatment. Is there a significant effect of the treatment as the hypothesis at alpha 0.05 level? So I'll show you the tutorial first, just I'm the independent sample T test. And then I'll go to SPSS and run for you. So tutorial can there's a separate data, okay? I've come before and after the aware. So there are eight participants. Onka pehle, I've come pre or post testing DVR before treatment, onka score kya tha and after treatment onka depression kya per score kya tha. So we need two sets of variables. Appellate just I'm a A key column kya ndar test scores aad kar liye tha, right? Ham ne soccer or swimmer players ke test ke upar ek column aad kye tha, but now for a repeated mayor T test, ham ne kya karna hai ki ham ne before ka column alag rakhna hai aur after ka column alag rakhna hai. So aapka one categorical independent variable hoga same jessa ki independent sample me us me group one or group two tha, lekin aab hamara time one time two testing hoga. One continuous dependent variable hamara hoga. Bilkul o se tarna se ish me hamara depression kya upar scores hai. Dono group group time one kya upar bhi aur time two kya upar bhi. SPS is kya ndar bilkul aise hi aap dekin ki jessa ye variable view hai aur is kya ndar aapka pehla column participant id hai. Dhusra column aapka before hai treatment aur isra column aapka after treatment hai. So aap ham ne do different columns use karne aur dono me alag rakh before treatment aur after treatment unka depression ba score kya aaya hai. Jab ham enter data karleenge dono ka alag rakh to is tarna se hamari. SPS is ki data file will look like this containing one variable before treatment one variable after treatment in third is a participants id. Aur similarly jessa ham ne pehle kya hai you will go to analyze, you will go to compare means and then you will go to paired sample T test. Repeated mayor bhi kya the paired sample bhi kya the matched sample T test bhi kya the. So you will select paired sample T test on the top menu. Once you select that aapke saamne jo window pop-up hoga that will be like this. So aap apna before and after dono send karenge as a variable one and variable two. So variable one would be pre-testing or before treatment in variable two will be after treatment ya post testing hoga. Us ke baat aap aap aap options ko klik karenge toh similarly wohi by default 95% confidence interval aaga wohi missing values ka jhumne abhi baat ki hai ki ham isko by default option ne ne dete hain kyunki hamara ek hi dependent variable hai. So we are not caring much about the missing values aur humare data mai hain bhi nahi. So one dependent variable ke saath we don't really need to see. So yeh bhilkul wohi hai. Then we'll click continue and then we will hit OK button aur uske baat aap ke paas output aayi ki.
