Hello, I'm doing a germination test, and I want to plot a graph to show the germination results. Here are two options:
First one, I can draw the graph on bar chart. Some seeds need one week germination, some need two weeks or more. Based on the required germination period, the graph can be plotted as a bar chart which the X axis is the required germination period. If the sample size is large enough, it should be closed to a Gaussian Curve, or normal distribution curve.
Second one is line curve. The total number of germinated seed should be increasing along with the time. Therefore, it is cumulative curve one the graph which the X axis is the time.
Here is the question, which one is better for showing the relationship between germination rate and time?
Both, but the bar chart is clearer because you don't have to explain that it is cumulative and it shows the actual data
line chart will be more clear to see the changes with minimum graphics
Germination curves (line chart) is the common way to show germination progress in time. As Mukesh Kumar already mentioned, it's more clear takes less graphics. Since gemination per time pointis is expected to have a normal distribution, the resulting germination curve will be an S-curve.
