what is bias? - error that is built into the study causes the results to be different from the truth (overestimation or underestimation of the association between exposure and outcome) where is the best place to prevent bias during a study? - the design stage (before you even look for results) name the four type of bias common in cross-sectional studies - selection bias interpretation bias recall bias non-response bias name the common types of bias in case-control studies? - selection b...

Regression Estimator Properties - Unbiasedness: This is the property that the expectation of the estimator is exactly the true parameter. What this means is that Beta_1_hat is an unbiased estimator for Beta_1 Model Parameter Interpretation - a positive value for Beta_1, then that's consistent with a direct relationship between the predicting variable X and the response variable Y Regression Analysis - Regression analysis is a simple way to investigate the relationship between 2 or more va...

The prediction interval of one member of the population will always be larger than the confidence interval of the mean response for all members of the population when using the same predicting values. (T/F) - correct answer True. See 1.7 Regression Line: Estimation & Prediction Examples "Just to wrap up the comparison, the confidence intervals under estimation are narrower than the prediction intervals because the prediction intervals have additional va...

theoretical validity ~ the degree to which a theoretical explanation developed from a research study FITS THE DATA and is therefore credible and defensible - internal validity ~ used when qualitative researchers identify POTENTIAL CAUSEAND-EFFECT RELATIONSHIPS - researcher makes mental comparisons external validity ~ used when researcher wants to GENERALIZE from a set of research findings to other people, settings, times, treatments, and outcomes statistics ~ a branch of ma...

Perception Final Study Guide (Quizzes and Test) Latest Update Graded A+ _________ is the processing of getting sensory stimuli into our brain and _________ is the process of the brain interpreting and making sense of that stimuli. sensation; perception So it seems that this thing we call "reality" is more complicated than we first thought. In Western philosophy, who do we give credit for first planting the seeds of doubt as to whether or not reality is what our sense perceive? plato ...

QMB 3200 UCF FINAL VOCAB ALREADY PASSED Parameter A numerical characteristic of a population, such as a population mean μ, a population standard deviation σ, a population proportion p, and so on. Target population The population for which statistical inferences such as point estimates are made. It is important for the target population to correspond as closely as possible to the sampled population. Sampled population The population from which the sample is taken. Sampling dis...
