Quantitative Report - Outlier?


I am doing a research project at the moment on change in health anxiety (HA) between 2018 and 2021 - I am using SPSS to analyse my collected data.
I have computed my variables HA_THEN and HA_NOW.
Next, I computed the variable HA_CHANGE, this was HA_NOW minus HA_THEN.

Once I calculated all the HA_CHANGE values, I noticed an outlier, therefore I went on data, select cases, if condition is satisfied, <1 and this excluded the outlier from my future tests.

My question at the moment is, in the write up, where do I comment on removing this outlier? Would it be on Participants within the methods section? Or would it be within the preparation of raw data in the results section?


Less is more. Stay pure. Stay poor.
Why would you remove an outlier if it wasn't an erroneous value? It has value.

So did you match individual (person) level values between the periods and find the differences?
