The one-sample t-test calculator provides a p-value with step-by-step calculation, confidence interval, effect size, test power, outliers, distribution chart, and a histogram.
30 pH measurements are sampled from one group representing bottled drinking water labeled "alkaline" available to the general consumer. We wish to compare this measured mean with an expected advertised value of 8.5. This is the exact situation for which one should employ a one sample t test!
Null (H0H0): No difference between sample mean and population mean (H0:μ=μ0H0μ0) Alternative (HaHa): Difference between the sample mean and population mean (H0:μ≠μ0H0μμ0) for a two-tailed test) 2. Sample Mean and Standard Deviation Calculation ...

How do you make a decision on a one-sample t-test? First, you need to know the t-statistic, which we calltobst_{obs}tobs, and the degrees of freedom df, so that you can compute the p-value. The process of calculation of the p-value will depend on the type of tails defined...
sample sizeAn improved method of sample size calculation for the one‐sample log‐rank test is provided. The one‐sample log‐rank test may be the method of choice if the survival curve of a single treatment group is to be compared with that of a historic control. Such settings arise, ...

A two- sample test tests the equality of the distributions of two samples. When testing for normality, please see [R] sktest and [R] swilk. Quick start One-sample test comparing the distribution of v1 with a Student's distribution with 5 degrees of freedom ksmirnov v1 = t(5,v1) ...
(calculation base on uM values, hence the additional factor 10E-6). -log([Secondary Screen -> IC50 (uM)(CDD)] * 10^-6) Geometric mean of the IC50 If you don't use pIC50s (you really should), then IC50 values can be averaged using the geometric mean, since they are based on ...
