Q

Any factor that is NOT directly related to the purpose of the study, but may affect the dependent variable. When these factors are not controlled, they exert a confounding influence on the independent variable, that is they contaminate the independent variable in such a way that their separate effects are obscured.

A

CONTENT BIAS

24
Q

a parametric test for comparing 2 means (for example this test is used when there is a single dependent variable, but a comparison between groups)

◦Example: Best means of analysis to use when you have a study of a new treatment technique, but have 2 groups – one participating for 30 minutes a day and one group participating for 60 minutes a day.

3 categories of quantitative research
1.Experimental 2.Descriptive 3.Mixed Experimental-Descriptive research
27
Standard deviation is the average amount that all scores in the distribution deviate from the mean. What does a small standard deviation indicate?
more homogeneity
28
there is a normal distribution of data
parametric statistical procedures
29
there is not a normal distribution of data
nonparametric statistical procedures
30
Which is more powerful? Parametric or nonparametric statistics?
Parametric statistics
31
just means the probability of the findings. For example, if the value is p<.05, that means the probability of that finding being true is 95% and the probability of the finding being false is 5%. And if we say that p<.01 that just means the probability of the findings being true are 99% and only 1% chance of the findings being incorrect. That is a very brief explanation of statistical findings
P value

considered to be the “gold standard” of true experimental designs. This type of design is considered the most rigorous

43
tool, assessment, or instrument used to test and see if the dependent variable was affected or changed by the independent variable

when the researcher reports a relationship between the intervention and the outcome (or progress) when no relationship (or progress) really exists.

refers to how well the measure correlates with an outside criterion The ability of an assessment to produce results that are in agreement with or predict a known criterion assessment
