Using JASP is mandatory.
A researcher is interested in testing which brand of coffee tastes better. Ten people were selected to participate in tasting four different types of coffee: Maxwell House, Folgers, Starbucks, and Tim Hortons. All coffee brands were made by the researcher from fresh grinds and the order in which each participant tasted the coffees was counterbalanced. After tasting each brand of coffee, participants rated the quality of taste on a 7-point scale (1 = terrible to 7 = delicious). It is hypothesized that the brands will differ in quality of taste and the data are in the file coffeeTasting.jasp (I have provided both a screenshot and a WeTransfer.com link https://we.tl/t-yX4iiU6v6C which contains the file ready to be opened on JASP, you just have to copy-paste it in your browser and open it).
