Line Graph, Histogram, and Stem & Leaf

Today we learned about stuff that we already learned in the past semester. Histogram and Stem & Leaf were new things for me. I already knew some info about the line graph. For line graph I learned a new word which is origin which means The perpendicular intersection of these axes. For histogram I learned that a bar graph and line graph combined are like a histogram. For Stem & Leaf I learned that it shows data arranged by place value. That is what I learned today and we also asked teachers for their age.
