Mann-Whitney U Test Calculator
Calculate Mann-Whitney U Test
Enter two sets of data to perform the Mann-Whitney U Test for comparing two independent samples.
The Mann-Whitney U Test Calculator is a scientifically designed tool to perform the Mann-Whitney U Test, a non-parametric statistical test used to compare two independent samples. Based on peer-reviewed methodologies, this calculator computes the U statistic to determine if there is a significant difference in the distributions of two datasets, making it an essential resource for researchers, statisticians, and professionals in fields like agriculture, biology, and social sciences. By inputting two sets of numerical data, users can assess differences without assuming normality.
Developed with insights from Agri Care Hub, this tool ensures reliability and user-friendliness. It supports applications in agricultural research, medical studies, and experimental design, where non-parametric tests are critical. The calculator uses the Mann-Whitney U formula: \( U = n_1 n_2 + \frac{n_1(n_1+1)}{2} - R_1 \), where \( n_1 \) and \( n_2 \) are sample sizes, and \( R_1 \) is the sum of ranks for the first sample, ensuring alignment with statistical standards.
The Mann-Whitney U Test is widely used to compare medians or distributions when data does not meet the assumptions of parametric tests like the t-test. This tool simplifies the computation, making it accessible for both academic research and practical applications in data analysis.

To use the Mann-Whitney U Test Calculator, follow these steps:
- Enter Sample 1: Input a comma-separated list of numerical values for the first sample (e.g., 10, 12, 15).
- Enter Sample 2: Input a comma-separated list of numerical values for the second sample (e.g., 11, 13, 16).
- Click Calculate: The tool will compute the Mann-Whitney U statistic and display the result.
Ensure all inputs are valid numbers separated by commas, with no spaces or non-numeric characters. Each sample should contain at least one value, though larger samples improve statistical reliability. For accurate results, consult statistical data or resources like Agri Care Hub for guidance on data preparation. Double-check inputs to avoid errors.
The calculator assumes independent samples and does not require normality. For small samples or tied ranks, results are approximate. For precise significance testing, consult statistical tables or software for p-values.
The Mann-Whitney U Test Calculator is ideal for scenarios requiring comparison of two independent samples without assuming normal distribution. Use it when:
