How to compute p-values and Cohen’s d for z-tests p-Values: The p-value of your sample is the lowest alpha level you could have used for your test and still rejected the null hypothesis given your sample. Consider the following example: You read in a newspaper that the mean SAT score of the nation’s high

Finding P-Values using the t-distribution Here is an example showing the three methods that you can use to find the P-Value when using the t-distribution. Example: Find the P-Value for a left-tailed test with n=27 and test statistic t = -1.500 Remember that the P-Value is the probability of getting a test statistic that is at least as

Calculation of P-Values Let’s repeat this for a right-tailed test. • Null hypothesis: = 0 • Alternative hypothesis: > 0 • Give the null hypothesis the benefit of the doubt and assume that it is still the case that = 0. • Now calculate the P–value which is the probability we would have chosen a sample of data with a mean as large as X.

To compute a p-value by hand all you do is find the area “outside” of the test ratio value from step 6 in ‘normal curve’ – that is your p-value. There are two areas “outside” of your test ratio from step 6 – one on each side of the normal curve.

very small P-value associated with it. So small, in fact, that your calculator rounds it to 0. Don’t be alarmed when this happens; just indicate that the P-value is “near zero.” The P-value won’t be exactly zero, but we are unable to find out just how low it is for extremely large values. 9.

Math 124: Using the t-table to find P-values Dr Ben Bolstad bolstad math124@bmbolstad.com May 13, 2005 There are fewer P-values in a t-table then in the normal distribution table we have used earlier. The method we use is to put bounds on the P-value (ie we want something of the form Lower bound < P-value
