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.
pg. 1
, 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.
