Science ✔✔Method of attempting to arrive at objective truths Use of evidence to make explanations and predictions of natural phenomena
Hypothesis ✔✔Proposed explanation for a problem or observations
Scientific Method ✔✔Process of creating explanations about the world and testing those explanations with experiments and data
Evidence-Based Practice ✔✔Three-pronged approach to working with clients
What are the 3x prongs of Evidence-based Practice ✔✔Weight of the evidence from scientific research Field observations Individual client needs and preferences
Prediction ✔✔Expected outcome generated from a hypothesis.
Steps of the Scientific Method (5x) ✔✔Idea - identify the problem Generate hypothesis
Design an experiment
Acquire and analyze data
Accept & keep testing OR Reject and generate a new hypothesis
True or False: Scientists identify what is most likely to be true by demonstrating what is not true. ✔✔True
Theory ✔✔Hypothesis or set of hypotheses for which a lot of high-quality evidence has been gathered
Anecdote ✔✔Account of a person's experience
Uncontrolled Variable ✔✔Variable in an experiment that scientists make no effort to change or account for
Primary Research ✔✔Original research
Scientists perform experiments & collect data
Secondary Research ✔✔Scientists analyze data that has already been collected or published
Observational Research ✔✔Observes ongoing behaviors in order to determine if correlations exist
Meta-Analysis ✔✔Statistical analysis of RCTs; a study of studies
Empirical ✔✔Based on observation or experience
Test-Retest Reliability ✔✔Getting similar results when something is measured under the same conditions
Reliability ✔✔consistency of measurement
Validity ✔✔Assessment of whether a tool is measuring what it is supposed to measure
Selection Bias ✔✔Sample of people is not representative of the larger population
Retrospective ✔✔Study that looks backward in time
Recall Bias ✔✔Inability to accurately remember past behaviors
Case Studies ✔✔Track a single person or group over time
Surveys ✔✔Questionnaires or interviews given to samples of people
Historical Research ✔✔Looks at events that already happened and uses them to make inferences about over times and the future
Cross-sectional Studies ✔✔Variables in a group at a specific point in time; a cross-section of people
Case-control Studies ✔✔Determine if exposure to something is associated with an outcome
Uses data that has already been collected
Cohort Studies ✔✔Group followed over time to see if there is a relationship between an exposure and an outcome/disease
Descriptive Research ✔✔Describes individuals or populations
Exploratory/Epidemiological Research ✔✔Looks for relationships between variables in large populations
Parallel Design ✔✔Track 2+ independent groups in parallel with each other
Factorial Design ✔✔Test the impact of 2+ variables at the same time instead of isolating a single variable
