30
Q

Point Estimation

Use of the value of a sample statistic as one’s estimate of the value of a population parameter

31
Q

Interval Estimation

A

Placement of a range of numbers around a point estimate

32
Q

Confidence Interval

A

An interval estimate inferred from sample data that has a certain probability
of including the true population parameter

33
Q

The branch of inferential statistics focused on determining when the null hypothesis can or cannot be rejected in favor of the alternative hypothesis

A

Hypothesis testing

34
Q

Null Hypothesis

A

a statement about a pop- ulation parameter; typically, it states that there is no relationship between the inde- pendent and dependent variables in the population.

35
Q

_________________ is the logical opposite of the null hypothesis (i.e., stating that there is a relationship between the independent and dependent variables in the population).

A

alternative hypothesis

36
Q

The___________ or ___________ use set by the researcher usually at .05 and it is the point at which the researcher would conclude that the observed value of the sample statistic is sufficiently rare under the assumption of the true null hypothesis.

A

Alpha level
Level of Significance

Or it is when you reject the null and go with the alternative`

37
Q

Independent Samples t test

A

The significance test of the difference between two means that uses the t probability distribution

38
Q

the __________ looks a lot like a normal curve; it’s just a little flatter and a little more spread out than the normal curve. Just like the normal curve, the t distribution has a mean of zero, is symmet- rical, is higher in the center, and has a “left tail” and a “right tail” that represent rare events.

A

t distribution

39
Q

he area on a null hypothesis sampling distribution where the observed value of the statistic, if it fell in this area, would be considered a rare event

A

Critical REgion

40
Q

The likelihood of the observed value (or a more extreme value) of a statistic, if the null hypothesis were true

A

Probability Value or pvalue

41
Q

The_______ is a value between 0 and 1, and it indicates the proportion of the area in the sampling distribution that lies at or beyond the value of your test statistic value

A

p value

  • The closer the p value is to zero, the less likely your test result would be if the null hypothesis were true. Therefore, a very small p value provides the evidence you need to reject the null hypothesis. A very small p value means that the value of your sample statistic would be a rare event if the null hypothesis were true.
42
Q

which means the finding (e.g., such as an observed difference between two means) is very likely a real relationship (i.e., not due to chance).

A

statistically significant

43
Q

Independent samples t test

A

Used to determine if the difference between the means of two groups is statistically significant

44
Q

An index of magnitude or strength of relationship

A

Effect size indicator

45
Q

effect size indicator tells you how much variance in the dependent variable is uniquely explained by the independent or predictor variable

A

partial eta squared

46
Q

an alternative hypothesis that includes a not equal to sign ( ).

A

nondirectional alternative hypothesis

47
Q

contains either a greater than sign (>) or a less than sign (

A

directional alternative

48
Q

If the researcher uses a ___________ and a large difference is found in the opposite direction, he or she can not conclude that a relationship exists in the population. That’s the rule of ____________—even if you find a large difference you must conclude that the difference is not statistically significant if it’s in the opposite direction from the one you hypothesized.

A

directional alternative hypothesis

49
Q

What are the 5 steps in hypothesis testing with decision making rules?

A
  1. state the null & the alter.
  2. Set the alpha level
  3. select the statistical test to be used
  4. Conduct the test and obtain the p value
  5. Compare the p value to the alpha level
50
Q

If p value is less than or equal to the alpha level, what do you do?

A

reject the null and tentatively accept the alternative

51
Q

If p value is greater than alpha?

A

Fail to reject the null and the research is not statistically significant

52
Q

What is a Type I error/

A

the researcher rejects a true null

Q

What is a type 2 error?

A

failure to reject a false null
