POS 3703 Final EXAM (updated 2026) Questions & Answers | Latest Already
Graded A+ UPDATE |2026
Test of Statistical Significance - (ANSWER)Decides whether an observed relationship between an
independent and dependent variable exists in the population.
Measure of Association - (ANSWER)How well the independent variable works in explaining the
dependent variable.
Null Hypothesis - (ANSWER)In the population there is no relationship between the independent and
dependent variable.
Ho
Alternative Hypothesis - (ANSWER)HA
Type I Error - (ANSWER)When the researcher concludes that there is a relationship when there is none.
Type II Error - (ANSWER)When the researcher infers that there is no relationship when there is one.
.05 Level of Significance - (ANSWER)The minimum standard.
If the p-value for a correlation coefficient is .005 it is significant at - (ANSWER)99% confidence.
Standard Error of the Difference - (ANSWER)1.) Square each mean's standard error.
2.) Sum the squared errors.
3.) Take the square root of the sum.
Confidence Interval Approach - (ANSWER)Uses standard error to determine the smallest plausible mean
difference in the population.

P-Value Approach - (ANSWER)Determines the exact probability of obtaining the observed sample
difference under the assumption that the null hypothesis is correct.
Two-Tailed Test of Statistical Significance - (ANSWER)Finding the upper and lower limits of random
sampling error.
Test Statistic - (ANSWER)Tells us how many standard errors separate the sample difference from zero.
Chi-Square Test of Significance - (ANSWER)Helps determine statistical significance when using nominal
and ordinal level data.
x2
What are the two types of data x2 can be used in the analysis of relationships between variables? -
(ANSWER)Ordinal-level data and nominal level data.
Critical Value - (ANSWER)Marks the upper plausible boundary of random error and defines Ho's limit.
Proportional Reduction Error - (ANSWER)Prediction-based metric, varies in magnitude between 0 and 1.
Symmetric Measure Association - (ANSWER)Takes on the same value.
Asymmetric Measure of Association - (ANSWER)Models the independent variable as the causal variable
and the dependent variable as the effect.
Lambda - (ANSWER)Measures the strength of a relationship between two categorical variables.
