|
Empirical Law
|
when a theory researches the level of absolute consistency in outcomes - allows for more precise predictions
theories can never be proven, only disproven |
|
|
Primary Goal of Evaluating Research Reports
|
to determine the worth or merit of a study, which ultimately depends upon the validity of the study

Inferential Statistics
|
decision making process that allows one to estimate population characteristics from sample data
|
|
|
Best Sample Is
|
Random
Representative Really Large |
|
|
Statistical Inference
|
success of this process (making valid conclusions) requires certain assumptions made concerning how well the sample represents the larger population: probability, sampling error
|
|
|
Probability
|
system of rules for analyzing a complete set of possible outcomes
|
|
|
Sampling Error
|
tendency for sample values to differ from population values (occurs by chance)
|
|
|
Use of Probability in Research
|
guideline for making decisions about how well sample data estimate the characteristics of a population
are observed differences likely to be representative of population differences or occurred simply by chance |
|
|
Sampling
|
Define Population
Inclusion Criteria Exclusion Criteria |
|
|
Sampling Error
|
values is called sampling error.
Sampling error of the mean for any single sample is equal to the difference between the sample mean (x) and the population mean (u). |
|
|
How can we prevent sampling error?
|
sample as close to population as we can - randomization, representative, large number
|
|
|
Standard Error of the Mean (definition)
|
estimation of the population standard deviation
|
|
|
Standard Error of the Mean (equation)
|
Standard Error = standard deviation / the square
root of the sample size (n) |
