Exactly what is a Stemplot?
Stemplots show a little more information than a histogram and have now been a t l that is common displaying data sets since the 1970s. They truly are typically used if you have a medium amount of quantitative variables to investigate; Stemplots greater than 50 observations are uncommon. The name “Stem plot” www.datingmentor.org/caucasian-dating/ comes while there is one “stem” with all the place-value digits that are largest to the left (shaded in grey in the image below) and another “leaf” towards the right.
