12CHAPTER THE INDEPENDENT-SAMPLES t TEST 12.1 RESEARCH SITUATIONS WHERE THE INDEPENDENT-SAMPLES t TEST IS USED The independent-samples t test is used to evaluate whether the means of a Y dependent variable differ significantly across two groups. This test is used much more often in actual ...
A t-test is used when you're looking at a numerical variable - for example, height - and then comparing the averages of two separate populations or groups (e.g., males and females). Requirements Two independent samples Data should be normally distributed The two samples should have the ...
Large independent samples are those that have 30 or more, and a z-test can be used to analyze the data. Learn how identifying the standard deviation, error, and z-test equation can examine data for the null hypothesis, or alternative hypothesis. ...
Thus, to provide 95% confidence intervals of the regression coefficients, we employed bootstrapping with 2000 samples. Table 2 summarizes the results of the backward regression with cross-validation for both models with performance-based physical function as dependent variable. While several indicators ...
Cell fractionation was performed 48 h post transfection and mitochondrial samples with same protein abundance were used for the PE assay. a,b,e,h, Data are the normalized mean ± s.d. Two-tailed one-sample Student’s t-test for comparisons to the siWIPI4 (a) or controls (b,e,...
Fits in a and c were conducted according to Supplementary Equation (1) (Supplementary Fig. 2). a and c show raw fluorescence data, whereas panel e is normalized by a single-site hyperbolic binding curve. Fit parameters for constructs in which LDS = 5 have been omitted from b and d...
The Plot of the Residuals of the Regression Equation — a Test for Detecting Overlooked, but Decisive Independent VariablesIn Figs. 33 (p. 118/119) and 34 (p. 122/123), drawn on the topographical map of the Simen mountains, the plot of the residuals is shown which result from the ...
If, however, the equation can be satisfied without all ki being equal to zero, the solution is called “nontrivial.” If a nontrivial solution can be found, then we say that the set of vectors is linearly dependent. If only the trivial solution is satisfied, the set of vectors is said...
For comparison of two samples of equal variance, statistical significance between groups were assessed using two-tailed, paired Student’s t tests (\(\alpha =0.05)\). For multiple sample comparisons of equal variance, ordinary one-way ANOVA was used followed by Tukey’s post-hoc analysis to ...
