I have no idea which tests to use to analyse my data. For example you can have age categories as "18 to 25", "26 to 30", "30 to 35" and so on. So why can't you WhatsApp today for training followed by one month of mentorship until you are very conversant with the entire analytics process and can write output results in the recommended format? We are going to need the COUNTA and COUTBLANK function to do that. /Filter/FlateDecode my name is Abrar-ur-Rahman Niloy. Your null hypothesis from what you've written is there is no difference in mean of question categories between conditions. Or should I select the median like you show and then use Wilcoxon mann-whitney to compare the responses to the advertisements between groups? N of Valid Cases 167. X = (x - a) / (b - a) 3 4.0 I am still having a hard time understanding (or more like being sure) maybe due to the translation to my language. I think youll find what youre looking for in Muijs, D. (2004). I also plan to use the MEDIAN Likert variables from two different ordinal Likert scales to test any correlation between these two scales (i.e., using Spearmans Rho). "Neutral" * 3, Y = (B - A) * (x - a) / (b - a) + A. It consists of a statement or a question, followed by a series of five or seven answer statements. We also need the help of the COUNTIF function.

Likert scales are the most broadly used method for scaling responses in survey studies.
Transforming different Likert scales to a common scale - IBM A common mistake is to calculate a numerical average, or mean value of the coded responses. © 2011-2022 Achilleas Kostoulas. hbbd``b`vS`_bE TqDoAw# b
