## Help with effectsize package

 Hello all, I am having some trouble with the effectsize package in R. I am trying to convert Z scores to percentiles using the convert_z_to_percentile command. This same code (below) has worked for 3 other variables, but not these 2 variables However, when I use the function to convert other z scores to percentiles, I get numbers that are exponential (e.g., 1.877030e+01) instead of a percentile. Has this happened to anyone else, and if so, how were you able to fix it? Here is my code: #generate z-scores for SSPA using the scale() function - this part of the code is successful dat\$varA_z <- scale(dat\$varA_tot, center = TRUE, scale = TRUE) dat\$varB_z <- scale(dat\$varB_tot, center = TRUE, scale = TRUE) #Convert z-scores to percentile for UPSA using effectsize package tool, convert_z_to_percentile #for some reason this isn't working dat\$varA_per <- (convert_z_to_percentile(dat\$varA_z)*100) dat\$varB_per <- (convert_z_to_percentile(dat\$varB_z)*100) Thank you in advance for any help you may be able to offer!

## Re: Help with effectsize package

 Hi Emma, You write "I get numbers that are exponential (e.g., 1.877030e+01) " 1.877030e+01 is scientific notation. It means 1.877030 * 10 ( = 18.7703). This seems like a perfectly good percentile.
