Chi Square Goodness Of Fit Calculator
Chi Square Goodness Of Fit: a planned Super Calculator tool. Covers observed counts per category. Stub page while the tool and its worked example are prepared.
Chi Square Goodness Of Fit Calculator is a planned calculator in the mathematics section of Super Calculator, covering statistics and probability.
What this calculator will compute
Inputs: observed counts per category, expected proportions or counts, parameters estimated and alpha.
Outputs: chi-square statistic, df, p value, per-cell contributions and decision.
Formula, recorded as scope and not yet verified against a primary source: chi-square = sum of (O_i - E_i)^2 / E_i with df = k - 1 - m, where k is the number of categories and m the number of parameters estimated from the data. Expected counts derive from the hypothesized proportions.
