Hello, I am conducting an experiment for my dissertation and looking at the effect that relaxing photos have at mood , physical and mental health. There is only one group that is going to be used for this study (there is no control group). Participants will be asked questions on mood, physical and mental health (3 dependent varibles ) presented with the photos (Indepented variable) and then asked the same questions prior to the exposure to photos. The point is to see if the photos will have an effect or what effect on these 3.
The problem is I dont know how to best analyse the data in SPSS and the steps I need to do, as well as find the sample size I need for the study using Gpower because I dont know what statistical test I am using and how to find the effect size.

This online calculator can also be useful depending on the specific analysis data.

First of all it should be clear whether the variables are categorical or interval, as that determines the choice of statistical test and even sample size calculations. Looking at the research question the photos appear to be categorical, and the outcomes of mood and health can be either measured on a linear interval scale, if such scale is availabel and is planned to use, or categorical variable. Once the data type is finalized and clear, appropriate statistical test are easy to chose and apply.
Some youtube channel have step by step guides for SPSS. Use mock data sets to perform tests and analysis, that is how we can learn by doing, and later apply to our real dataset.
