WebFor these data, weight has a range of approximately 90 – 31 = 59 kilograms and for height it is 1.67 – 1.33 = 0.34 meters. Note: When you’re assessing mathematical functions rather than data values, the range of f(x) appears on the y-axis (outputs), and the domain is on the x-axis (inputs).

WebThe third and last step is to compare each of the \(k(k-1)/2\) test statistics against its corresponding critical \(r_{ij}\) value. Those pairs that have a test statistic that exceeds the critical value are significant at the \(\alpha\) level.

They go arm in arm, like Tweedledee and Tweedledum. Here's why. When you perform a t-test, you're usually trying to find evidence of a significant difference between population means (2-sample t) or between the population mean and a hypothesized value (1-sample t). The t-value measures the size of the difference ...
