How to use thettest calculator Choose yourdata entry format. This will change how section 3 on the page looks. The first two options are for entering your data points themselves, either manually or by copy & paste. The last two are for entering the means for each group, along with the ...
This calculator will tell you the one-tailed and two-tailed probability values of a t-test, given the t-value and the degrees of freedom. Please enter the necessary parameter values, and then click 'Calculate'. Degrees of freedom:
As long as you’re using statistical software, such asthis two-sample t test calculator, it’s just as easy to calculate a test statistic whether or not you assume that the variances of your two samples are the same. If you’re doing it by hand, however, the calculations get more comp...
Enter either the p-value (represented by the blue area on the graph) or the test statistic (the coordinate along the horizontal axis) below to have the other value computed. Student's t-distribution Other distributions:Normal•Chi-square•F ...
This calculator will tell you the observed power for a one-tailed or two-tailed t-test study, given the observed probability level, the observed effect size, and the total sample size. Please enter the necessary parameter values, and then click 'Calculate'. ...
The calculator assumes that all samples have the same Skewness and Kurtosis. Monte Carlo Simulation The data for minimum sample size formulas are derived from extensive Monte Carlo simulations for n = 2 to 2000. Observed alpha values were determined empirically from the p-values of 100,000 replic...
(Promega) at 0 h and 72 h according to the manufacturer’s protocol. Each data point represents quadruplicates and experiments were repeated at least twice. IC50 values were calculated, using the GR calculator atwww.grcalculator.org. Proliferation assays with lenalidomide were performed in ...
A two-tailed t-test’s p-value. This value can be found by enteringt = 1.758570846with18degrees of freedom into anyTScore toPValue Calculator. In this situation, the value ofpis0.095639932. Because this is greater than0.05, we cannot reject the null hypothesis. This suggests that we lack ...
The cells and tumors from mice with and without treatments were collected, and the total RNA was isolated using trizol reagent (Invitrogen, Massachusetts, USA) following the manufacturer’s protocol. The concentration and purity of RNA were determined using the GeneQuant RNA/DNA Calculator (Pharmacia...
88 Methylation β values for CpG sites were calculated and values were input into a DNA Methylation Age Calculator30 to predict epigenetic biomarkers for aging (DNAm PhenoAge) and aging acceleration, determined by the correlation between DNAm PhenoAge and chronological age (DNAm PhenoAgeAccel, ...
