In both cases, the denominator is the square root of the variance, like so: For X, Z = (X-μ) / σ. For X̅, Z = (X̅ - μ) / (σ / √n) This fits with what we know about the central limit theorem. For X, the variance is σ².

WebThus, the t-statistic measures how many standard errors the coefficient is away from zero. Generally, any t-value greater than +2 or less than - 2 is acceptable. The higher the t-value, the greater the confidence we have in the coefficient as a predictor. Low t-values are indications of low reliability of the predictive power of that coefficient.
