1 0 1 1 Explain the correct way to set up various graphs. Explain how to determine what type of graph you should use for a set of data. 1 4 2 Graphing in Science Parts of a graph (applies to histogram, line graph, double bar graph) I. Horizontal axis a. also known as x-axis b. independent/manipulated variable 0 0 1 1 0 0 1 0 1 0 1 0 1 1 0 1 0 0 0 1 0 1 0 0 0 1
i.1 In1 bar or histogram: choices or intervals ii. In line graph: dates, time, days, etc. II. Vertical axis a. also known as y-axis b. dependent/ responding variable i. In bar or histogram: scale based on range of data ii. In line graph: scale based on range 1 4 2 Graphing in Science Parts of a graph (applies to histogram, line graph, double bar graph) III.
