If you want to test whether means are more similar than chance would likely produce under the null, then compute the left tail probability. $\endgroup$ –

WebApr 22, 2024 · The alternative hypothesis can be either two-tailed, left-tailed, or right-tailed: H 1 (two-tailed): μ ≠ μ 0 (population mean is not equal to some hypothesized value μ 0) H 1 (left-tailed): μ < μ 0 (population mean is less than some hypothesized value μ 0) H 1 (right-tailed): μ > μ 0 (population mean is greater than some hypothesized ... WebAlternative Hypothesis. The statement that there is some difference in the population (s), denoted as H a or H 1. When writing hypotheses there are three things that we need to know: (1) the parameter that we are testing (2) the direction of the test (non-directional, right-tailed or left-tailed), and (3) the value of the hypothesized parameter.
WebIn probability theory and statistics, skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean. The skewness value can be positive, zero, negative, or undefined. For a unimodal distribution, negative skew commonly indicates that the tail is on the left side of the distribution, and positive skew … WebWith right-skewed distribution (also known as "positively skewed" distribution), most data falls to the right, or positive side, of the graph's peak. Thus, the histogram skews in such a …
