I am calculating variance and standard deviation for my statistics class, however my hand calculations are not matching with JASP calculations, which we were asked to cross check our work. My mean/median/mode all match JASP, however the JASP variance and standard deviation is showing a large discrepancy. I don't understand the large discrepancy, is there something I'm missing?

The first picture is my hand calculations, the second picture is the table from JASP. My sample size is 20.
