Question

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 graphical display should she use? Explain.

Answer 1

Height of plant vs Month graph?

Answer 2

No like what kind of graph should she use and why?

Answer 3

Histogram, circle graph, bar graph, etc. What kind of graph should she use?

Answer 4

X-Y graph where X axis records the height of the plant and Y-axis is the month( in this case 4 weeks)

Answer 5

That type of graph wasn't mentioned in the text. So it has to be a different graph.

Answer 6

Actually X-Y graph is a more common way of representing this data but since you say its not mentioned in the text, then I think the next best option to this would be using a histogram.

Answer 7

Okay :) but why?

Answer 8

A bar graph can only show one comparison (so you either choose the height or the month of the plant) and compares between different set categories(meaning different types of plants)but in your case you are only interested in 1 plant and the same plant rgt?
So the bar graph cannot be it.

Answer 9

My choices

bar graph categorical compares categorical data
circle graph categorical compares data as parts to a whole
histogram numerical uses intervals to compare quantities
scatter plot numerical shows trends in data
line graph numerical shows changes in quantities over time
stem-and-leaf plots numerical organizes data in numberic order
box-and-whisker plots numerical organizes data into four equal groups

Answer 10

numeric* my bad

Answer 11

In that case the line-graph would be the most appropriate because it is somewhat similar to the X-Y graph and can record the plant's values which is(height over time)
