How do you know if a relationship is significant?
To determine whether the correlation between variables is significant, compare the p-value to your significance level. Usually, a significance level (denoted as α or alpha) of 0.05 works well. An α of 0.05 indicates that the risk of concluding that a correlation exists—when, actually, no correlation exists—is 5%.
Which of the following is a statistical measure of the relationship between two variables?
The correlation coefficient is a statistical measure of the strength of the relationship between the relative movements of two variables. The values range between -1.0 and 1.0. A calculated number greater than 1.0 or less than -1.0 means that there was an error in the correlation measurement.
What’s the meaning of cognitive dissonance?

What is the foot in the door phenomenon quizlet?

What does it mean when a difference between two groups is statistically significant?

Who used the method of introspection to scientifically?

How do you know if a t test is significant?
Compare the P-value to the α significance level stated earlier. If it is less than α, reject the null hypothesis. If the result is greater than α, fail to reject the null hypothesis. If you reject the null hypothesis, this implies that your alternative hypothesis is correct, and that the data is significant.
What is a significant relationship in statistics?
The Meaning of Statistical Significance. If a relationship between two categorical variables is statistically significant it means that the relationship observed in the sample was unlikely to have occurred unless there really is a relationship in the population.

|---|---|
| Term correlation | Definition a measure of the extent to which two factors vary together, and thus of how well either factor predicts the other |
Which best describes the foot in the door phenomenon?
The foot in the door technique is a compliance tactic that assumes agreeing to a small request increases the likelihood of agreeing to a second, larger request. So, initially you make a small request and once the person agrees to this they find it more difficult to refuse a bigger one (Freedman & Fraser, 1966).
Which measure of variation is most affected by extreme scores *?
The Median. An extreme score will skew the value to one side or the other.
What is the point to remember in regards to the effects of attribution?
