18 maj 2021 · A one sample t-test was performed to compare [variable of interest] against the population mean. The mean value of [variable of interest] (M = [Mean], SD = [standard deviation]) was significantly [higher, lower, or different] than the population mean; t (df) = [t-value], p = [p-value].

29 kwi 2022 · Student’s t table is also known as the t table, t-distribution table, t-score table, t-value table, or t-test table. A critical value of t defines the threshold for significance for certain statistical tests and the upper and lower bounds of confidence intervals for certain estimates.
31 lip 2023 · What is a t-test? A t -test is used to compare the means of two normally distributed populations. In the exam the population variance will always be unknown. What assumptions are needed for the t-test? The underlying distribution for each variable must be normal. In the exam you will need to assume the variance for the two groups are equal.
