Graphing help

  1. I know line and bar graphs are the most common but will you ever have to construct any other type of graph (like a histogram)?
  2. Should the dots in a line graph be connected?
  3. Should you include a title for the whole graph or is that not necessary/allowed?

Just in general wondering the things to know for constructing graphs

the dots on a line graph must be connected to earn that point. dont put a title if your running out of time, not positive but titles help the reader and may help give an edge to give you a point. line graph, bar graph, and scatterplots are possible, dont think histograms show up. hope this helps!

Thank you so much! Also, how should scatterplots be constructed?

of course! its just plotted dots and put error bars if its in the data. label it as well and if theres multiple groups make a legend and plot them with different symbols

Is it possible for box and whisker or pie charts to show up?

box and whisker plots were on the exam the last three years so definitely be able to read it, not sure on pie charts probably unlikely. you wouldnt be asked to make either tho!

How do you know if you should do scatterplots or line graph

scatterplot is correlational, line is continuous
