I have used a survey to research willingness to pay regarding virtual goods in videogames. For this, I have asked the respondents a couple of questions via Likert scale, to get their opinions on certain statements. I then asked them if they had ever purchased virtual goods before.
In this case, I want to see if satisfaction with the game leads to a higher likeliness of purchasing virtual goods. How would I go about testing this statistically? My first idea was to convert my Likert data to numerical values, E. G. from strongly disagree = 1 to strongly agree = 5. However I can't seem to find which type of test I should use to then see if there is any correlation between a higher satisfaction value and buying virtual goods.
