Pearson correlation r of log t90 and FITS1 = 0.975. P-Value = 0.000. If you look back to page 19, bottom, you will see that the correlation between log t90 and log t50 is also .975. That is, the correlation between the fitted (predicted) values and the observations y is the same as the correlation between the two variables x = log t50 and y ...

The p-value is labeled as “Sig.” in the SPSS output (“Sig.” stands for significance level). To find the correct “Sig.”, look in the section of the “Independent Samples Test” output labeled “t-test for Equality of Means” and you will find a column labeled “Sig. (2-tailed).” This is the correct column, not the column ...

Since the growing perpetuity formula values the dividend payment as of the end of year 4, discount that value back 4 years to calculate the PV of the dividend payment as of today, year 0. Remember that the dividend in year 5 is $2.12 (=$2 ( 1.06). P = Div3 / (1+r)3 + Div4 / (1+r)4 + [Div5 / (r – g)] / (1+r)4

The P-Value Method (only for proportion and mean with σ known) Calculate the p-value for your test statistic. If you are doing a left-tailed test, the p-value is the area under the standard normal curve (so use your table) to the left of your test statistic. If you are doing a right-tailed test, it is the area to the right of your test statistic.

P(x2) =P(x=0) + P(x=1) + P(x=2) = 2c+3c + 4c = 9c = 9/14. Alternatively, P(x2) = 1- P(x>2) = 1- P(x=3) = 1- 5c = 1- 5/14=9/14. Mean and Variance of a discrete r.v. with probability distribution. The mean (The mean of a r.v. is also called as the . expected value.) The variances . The standard deviation = Ex. Toss a coin twice, x = # of heads ...

The smaller the p-value, the stronger the evidence against the null model. There are no hard-and-fast cut-off values for gauging the smallness of a p-value, but generally speaking: A p-value above .10 constitutes little or no evidence against the null model. A p-value below .10 but above .05 constitutes moderate evidence against the null model.

The p value for the F statistic is < .05. This means that at least one of the independent variables is a significant predictor of the DV (standardized reading scores). The “Sig.” column in the Coefficients table shows which variables are significant.

You would then have to calculate the critical value for the t distribution at the desired α level, as described above, and make the comparison appropriate for your decision rule. You can also calculate the two-sided P value using the absolute value of the result you got for t*. The R command to get the two-sided P-value is:
