The P-value is very small. We would reject the null hypothesis that being female doesn’t matter for wage determination, after controlling for education. See Section 17.7 for more. 4) How to create a double-log functional form with dummy variables? You cannot take the natural log of …

You do NOT have to calculate critical values. SPSS will provide the EXACT significance value as a p value. All you have to do is understand what the p value means and report it in your results. Interpreting significant p values: You can report p < .05, p < .01, or p < .001 as it fits your results. You can also simply report the exact p value.

4. Look up the Chi-square value in a table to see if it is big enough to indicate a significant difference in handedness of males and females. Interpretation . Greater differences between expected and actual data produce a larger Chi-square value. The larger the Chi-square value, the greater the probability that there really is a significant ...

Another value that is given with spirometry is the FEF25-75, or mid-flow rate. This is a measurement of what flow is like during the middle 1/2 of a forced breath. Although often said to be a measurement of small airways obstruction, the FEF25-75 is fairly non-specific and reductions can be seen with a number of non-obstructive diseases.

In the above example the p-value is .002, implying that the difference in means is statistically significant at the .1, .05. and .01 levels. Summary: To find the p-value for the hypothesis test for the difference in means, look in the column labeled “Sig. (2-tailed)” in the “t …

The chance is reported as the p-value. A p-value close to 1 means that it is very likely that the hypothesized and sample means are the same (assuming that they are the same), and a small p-value (for example 0.01) means it is unlikely (only a one in 100 chance) that such a difference would occur by chance (again, assuming that the two means are the same).
