The logic behind this is that if the null hypothesis were really true, such result would be a rather ‘rare’ outcome. The x axis in figure 1 doesn’t display the value of the test statistic (Z in this case) as would usually be the case. For clarity sake the concrete difference in ...
"chi2gofcompares the value of the test statistic to a chi-square distribution with degrees of freedom equal to nbins - 1 - nparams, where nbins is the number of bins used for the data pooling and nparams is the number of estimated parameters used...
Calculate the test statistic and the p-value when {eq}\bar{x} {/eq} = 140, {eq}s {/eq} = 50, and {eq}n {/eq} = 100. Use a 5% significance level. {eq}H_0: \mu = 150 {/eq} {eq}H_1: \mu < 150 {/eq} Populat...
Calculate the likelihood ratio test statistic.David Gerard
Divide the total "D" by the "divisor" to find the t-value statistic for the dependent-samples t-test. TL;DR (Too Long; Didn't Read) Compare the obtained t-value statistic to the "critical t-value" found in your distribution t-table chart to determine whether you should reject the nu...

Degrees of Freedom Degrees of freedom are the measurements of the number of values in the statistic that are free to vary without influencing the result of the statistic. Statistic tests, including the Chi-Square, are often based on very precise estimates based on various pieces of vital informa...
How Is P-Value Calculated? P-values are usually calculated using statistical software or p-value tables based on the assumed or knownprobability distributionof the specific statistic tested. While the sample size influences the reliability of the observed data, the p-value approach to hypothesis te...
A confidence interval is a range of values, bounded above and below the statistic's mean, that likely would contain an unknown population parameter. Confidence level refers to the percentage of probability, or certainty, that the confidence interval would contain the true population parameter when ...
