Question:
What is another name for the standard deviation of a distribution of sample means?
Answer:
Standard error
Question:
Calculate the standard error of a distribution of sample means for a sample size of 50 and a
population standard deviation (σ) of 2.5.
Answer:
2,5/ sqrt(5)= 0.35
Question:
What term refers to the likelihood of a certain outcome occurring?
Answer:
Probability
Question:
What term is used to delineate a sample statistic that deviates from a population parameter to a
degree that appears to be beyond chance?
Answer:
statistically significant
Question:
, What is the general value that is used to determine statistical significance?
Answer:
0.05
Question:
Which of the following terms describes a claim that is made about a particular population
parameter?
Answer:
hypothesis
Question:
What is the difference between the null and alternative hypotheses?
Answer:
Question:
Describes some of the major problems with hypothesis testing.
Answer:
The significance level is an arbitrary value. Hypothesis testing is sensitive to sample size. P-values
do not reflect the size of an effect Hypothesis testing is often used as the only means to determine
significance. The results of hypothesis testing are frequently misinterpreted and misunderstood.
There is a publishing bias towards statistically significant results.
Question:
What is the purpose of a significance level?
Answer:
The significance level (α) is the value that the P-value of a test statistic can be compared to in order
to determine statistical significance. This value is typically 0.05.
