Research midterm

There is an independent variable in correlation

Which arepart of Level 1 heirarchy of evidence

Statistical process that yields an equation which allows for prediction

Quasi-experimental designs include 2 of 3 elements of a true experiment

Asking people questions at a mall is an example of which method

Excessive drop out rate:

Drink sizes (16 oz., 24oz., 30oz.) is an example of:

This type of method works like a referral program

What level of measurement has a true zero

Randomly selecting names from a hat is an example of which sampling method:

Classificatory scale is what type of measurement

100 female employees and 200 male employees- random sampling of selecting 20 females and 40 males. This is example of:

Blood type is an example of:

Response rate that we strive for is

Which is Not a sampling probability method

Single value that represents the best estimate for the population

Procedure that allows estimation of population characteristics from sample data

You use parametric tests on Nominal and Ordinal data

Conclusion formed by considering known facts is known as:

Internal validity is focused on cause-effect relationships

Is a study guide more effective than no study guide for increasing scores on a research midterm? Is an example of:

The closer to what number is the correlation weaker?

You reject the null hypothesis if value is statistically significant

What percent falls within 1 standard deviation?

Which is not a type of research

Distribution of scores that fall evenly around the mean score

Independent measure is most likely your:

Sample size influences inferential difference

What is NOT a threat to internal validity

Beta is what type of error

This scatter plot is an example of:

P-value is the difference in what type of values

If P value is less than alpha, we fail to reject the null

The p-value demonstrates statistically significant difference

If sample is not representative, it could lead to a sampling error, which is:

Which is NOT part of PICO

Exploratory research looks for cause and effect

If mean of group A = mean of Group B, we fail to reject the null

Variance is the spread of observations around the mean

Case-studies are the most classic way to infer causation

True experiment must have all of the following EXCEPT:

Average of group scores

Calculation of two points between the point estimate

Comparing two or more conditions for the purpose of determining the cause-effect relationship
