This affects the probability associated with any given t-value. For 5 and 30 degrees of freedom, a t-value of 2 in a two-tailed test has p-values of 10.2% and 5.4%, respectively. Large samples are better! I’ve showed how t-values and t-distributions work together to produce probabilities. politik präsentation ideen https://cliveanddeb.com
