SIRBL

Question 1

Statistics used to analyze nominal and ordinal data are referred to as

Answer 1

nonparametric tests.

Question 2

do not involve the use of any population parameters. In other words, mean and standard deviation are not needed, and the underlying distribution does not have to be normal.

Answer 2

Nonparametric tests

Question 3

is a nonparametric statistical test used for comparing categorical information against that we would expect based on previous knowledge. As such, it tests the observed frequency against the expected frequency

compares how well an observed frequency distribution of one nominal variable fits some expected pattern of frequencies

the data are in frequencies

Answer 3

The Chi-Square (X2) Goodness-of-fit Test

Question 4

*related in chi square

simply count how many individuals from the sample are in each category

Answer 4

Observed Frequency

Question 5

Is a statistical technique for finding the best-fitting straight line for a set of data. The resulting line is called the regression line.

Answer 5

Regression

Question 6

is used when you want to predict variables. (e.g., how much will be the jeepney fare if the distance is 5 kilometers?)

Answer 6

Regression

Question 7

is a model building.

Answer 7

Regression

Question 8

The is used to determine whether a sample comes from a population with a specific mean.

Answer 8

one-sample t-test

Question 9

The ________________ is a parametric statistical test that compares the means of two different samples of participants. It indicates whether the two samples perform so similarly that we conclude they are likely from the same population or whether they perform so differently that we conclude they represent two different populations.

control vs treatment group design

Answer 9

independent-groups t-test

Question 10

The ____ compares the means between two related groups on the same continuous, dependent variable.

Answer 10

dependent t-test (called the paired-samples t-test in SPSS Statistics)

Question 11

-assumes that the source population is normally distributed

Answer 11

Parametric Tests

Question 12

-does not make assumptions on the source population

Answer 12

Non-parametric tests

Question 13

is a type of inferential statistic used to determine if there is a significnt difference between the means of two groups, which may be related in certain features.

Answer 13

T-test

Question 14

is a statistical test that is used to compare the means of two groups.

it is often used in hypothesis testing to determine whether a process or treatment actually has an effect on the population of interest, or whether two groups are different from one another.

Answer 14

T-test

Question 15

Is there a difference between a group and the population

Answer 15

One Sample t-test

Question 16

Is there a difference between two groups

Answer 16

Independent T-test

Question 17

Same group measured twice
pre and post test

indicates whether there is a difference in teh sample means and wheteher this difference is great than would be expected based on chance

includes two scores for each person

Answer 17

Paired T-test

Question 18

is there a difference in a group between two points in time

Answer 18

Paired samples t-test

Question 19

Correlation is a statistical technique that is used to measure and describe the relationship between two variables.

neither variable is manipulated.

Answer 19

Correlation

Question 20

*Related with correlation

in which higher scores on one variable tend to be associated with higher scores on the other.

Answer 20

positive relationship,

Question 21

*related with correlation

is one in which higher scores on one variable tend to be associated with lower scores on the other.

Answer 21

A negative relationship

Question 22

Is a hypothesis testing procedure that is used to compare the differences in the means of two or more groups.

can compare two or more treatments.

Answer 22

ANOVA

Question 23

• the variable that distingiushes the groups in ANOVA is called

Answer 23

Factor (independent variable)

Question 24

The invidual conditions or values that define the factor in ANOVA are called the

Answer 24

Levels of the factor

Question 25

Is used in conjunction with ANOVA to identify exaclty the comparisons that have a significant difference.

Answer 25

Post hoc test
