Math; Appropriate Displays
A botanist records the height of a plant every day for a month. She wants to create a graph to show how the plant's height changed over the month. What type of display should she use? Explain.
Scatter Plot because, A simply X-Y axis line graph is a good choice for this. On the X axis she will have the height of the plant (make sure to label the axis, and identify the units of measurement -- e.g., centimetres or inches).On the Y axis she will have thirty spaces, one for each day of the month -- make sure to label that axis as well, and to clearly define the time period.She will end up with a line that starts at 0 and extends upward diagonally, which will give a really clear illustration of the plant's growth.
A coffee shop sells five different flavors of coffee. They want to compare how much of each is sold on Saturday morning. Which graph would be the best?
