Replicates and error bars
|
When you collect scientific data, you almost always collect replicate data and plot the individual replicates or an error bar showing the variability of the data. One of Prism's strengths is its ability to handle replicates and error bars.
| • | You can enter replicates directly into a Prism data table. |
| • | If you enter replicate values, Prism can plot either individual replicates or error bars. |
| • | You do not need to enter SD or SEM values in order to plot them. Prism can plot error bars from raw data. |
| • | You do not need to run a Row Means analysis to plot error bars. Prism can plot error bars directly from raw data. |
