To find the p values for the f test you need to consult the f table. Use the degrees of freedom given in the ANOVA table (provided as part of the SPSS regression output). To find the p values for the t test you need to use the Df2 i.e. df denominator.

What is F in ANOVA table?

The F ratio is the ratio of two mean square values. If the null hypothesis is true, you expect F to have a value close to 1.0 most of the time.The P value is determined from the F ratio and the two values for degrees of freedom shown in the ANOVA table.

What is an F value in ANOVA?

The F-value in an ANOVA is calculated as: variation between sample means / variation within the samples. The higher the F-value in an ANOVA, the higher the variation between sample means relative to the variation within the samples. The higher the F-value, the lower the corresponding p-value.

What is p-value example?

P Value Definition
A p value is used in hypothesis testing to help you support or reject the null hypothesis. The p value is the evidence against a null hypothesis.For example, a p value of 0.0254 is 2.54%. This means there is a 2.54% chance your results could be random (i.e. happened by chance).

How do you find the p-value from a test statistic and sample size?

When the sample size is small, we use the t-distribution to calculate the p-value. In this case, we calculate the degrees of freedom, df= n-1. We then use df, along with the test statistic, to calculate the p-value.

How do you find the p-value in a normal distribution?

The p-value is calculated using the sampling distribution of the test statistic under the null hypothesis, the sample data, and the type of test being done (lower-tailed test, upper-tailed test, or two-sided test). The p-value for: a lower-tailed test is specified by: p-value = P(TS ts | H 0 is true) = cdf(ts)

Test of significance: the P-value is calculated according to Sheskin, 2004 (p. 542). A standard normal deviate (z-value) is calculated as ln(RR)/SE{ln(RR)}, and the P-value is the area of the normal distribution that falls outside ±z (see Values of the Normal distribution table).

What is an F value in statistics?

A higher bit rate is better, so a 256 kbps MP3 or AAC file is better than a 128 kbps file.
