Mean, SD, SEM, 95% CI, N. In Prism:

Together, Emily and Rachel used the GraphPad Calculator to analyze the data and create several different graphs. They were able to visualize the results in various ways, which helped them to better understand the trends and patterns in the data.

Determine how many subjects you need to reach a statistically significant conclusion, preventing "underpowered" studies that waste resources. 4. Specialized Scientific Calculators graphpad calculator

Compare 3+ groups (e.g., dose-response). In Prism:

"How much NaCl do I need for 100mL of 0.9% saline?" Mean, SD, SEM, 95% CI, N

The suite is divided into several categories, each tailored to a specific stage of the scientific process. 1. Statistical Comparison Calculators

Unlike a standard calculator that just gives a number, the GraphPad Calculator provides immediately. Determine how many subjects you need to reach

This is one of the most cited tools in the GraphPad suite. It helps you objectively identify and decide whether to exclude a single outlier from a normally distributed dataset based on a chosen significance level (alpha). 3. Experimental Design and Randomization Good science starts before the data is even collected.

This is the most frequently used section. It allows researchers to determine if the differences between groups are statistically significant.

Used to analyze contingency tables. For example, Fisher's exact test is a go-to for small sample sizes in clinical research.
