Agreement and Validity Tests
HTMT Discriminant Validity Statistical Calculator
Calculate the heterotrait–monotrait ratio between two multi-item constructs.
Calculated result
When to use
Calculate the heterotrait–monotrait ratio between two multi-item constructs.
Formula or algorithm
HTMT is the mean absolute cross-construct correlation divided by the geometric mean of average within-construct correlations.
Assumptions and limits
Use the variable scales and sampling design required by this named statistical method. Review missing values, independence or pairing, outliers, and distribution or model assumptions before interpretation. Confirm that the selected dependent, independent, grouping, time, item, rater, or matrix variables match the research design.
Use Raw Data, Excel, or CSV
Upload XLSX, CSV, TSV, TXT, JSON, or pasted data where applicable; inspect cleaning, select the required variable roles, and review mapped inputs before calculation.
Uploaded files are processed locally in the browser. The cleaning report appears before variable dropdowns, and the selected cleaned columns are placed into this exact calculator rather than a generic fallback method.

How the HTMT Discriminant Validity Calculator Works
HTMT is the mean absolute cross-construct correlation divided by the geometric mean of average within-construct correlations.
The calculation runs in your browser. Submitted values are validated for the required numeric range, data shape, units, and method-specific restrictions before a result is shown.
Assumptions and Checks
- Use the variable scales and sampling design required by this named statistical method.
- Review missing values, independence or pairing, outliers, and distribution or model assumptions before interpretation.
- Confirm that the selected dependent, independent, grouping, time, item, rater, or matrix variables match the research design.
Required Inputs
- Item correlation matrix (required)
- Construct A item indices, 1-based (required)
- Construct B item indices, 1-based (required)
Results Reported
The result panel shows the final answer together with the intermediate quantities needed to audit the calculation. Depending on this method, reported values include:
- Construct A Items
construct_a_items - Construct B Items
construct_b_items - Mean Heterotrait Correlation
mean_heterotrait_correlation - Monotrait Geometric Mean
mean_monotrait_geometric - HTMT

How to Use the Calculator
- Confirm that the calculator title and method match the quantity, test, conversion, or planning question you need to solve.
- Enter values with compatible units and the requested sample, group, matrix, count, date, or option format.
- Select Example Data to inspect a valid input layout, or enter your own values and select Calculate.
- Review the result table, formula, worked substitutions, warnings, and interpretation rather than using only the headline number.
- Use Copy Result or Download CSV when you need a reusable record of the displayed calculation.
Understanding the Result
Interpret the estimate, uncertainty, test statistic, p-value, effect size, and diagnostics for the selected variables and design.
Review the formula, units, assumptions, and result interpretation before using the calculation.
Keep the entered values, units, selected options, and any warning shown beside the result. For a hypothesis test, report the statistic, degrees of freedom where applicable, p-value, alpha level, effect size, and decision. For an estimate or conversion, report the formula convention and final unit.
How to Report the Result
Report the method, selected variables, sample information, estimate or statistic, uncertainty, p-value when applicable, and practical conclusion.
Accuracy and Limitations
The calculator keeps full browser precision during calculation and rounds only for display. Accuracy still depends on correct inputs and on whether the displayed model represents the real problem. Educational calculators cannot replace required professional review, current official rules, field measurements, laboratory methods, or specialist statistical software where those are necessary.
