Online Biomedical Research Data Analyzer
Compare two independent groups using descriptive statistics and t-test.
Enter your numerical data for each group below. Each value should be on a new line.
Results will be displayed here after you enter data and click "Analyze Data".
Data Formatting Guide
- Enter one numerical value per line.
- Do not include units, symbols (like $, %), or commas.
- Blank lines or lines with non-numeric text will be ignored.
- Both groups must have at least two data points to perform a t-test.
Explanation of Terms
- Mean
- The average of the data points.
- Median
- The middle value of a dataset when it is sorted in order.
- Standard Deviation (SD)
- A measure of the amount of variation or dispersion of a set of values.
- T-Test
- A statistical test used to determine if there is a significant difference between the means of two groups.
- P-value
- The probability of obtaining results at least as extreme as the observed results, assuming the null hypothesis is correct. A p-value less than 0.05 is typically considered statistically significant.
Degrees of Freedom (df): ${tTest.degreesOfFreedom}
Interpretation: ${interpretation}
This interpretation assumes a two-tailed test with an alpha level of 0.05. For a precise p-value, use the t-statistic and degrees of freedom in a p-value calculator.
