The given terms.

Answer to Problem 1E

Solution:

The definitions of the terms are stated below.

Explanation of Solution

  • Individual differences: These are personal characteristics that differ from one participant to another.
  • Differential effects: The Differential Outcomes Effect is a theory in Behaviorism, a branch of psychology that shows that a positive effect on accuracy occurs in discrimination learning between different stimuli when unique rewards are paired with each individual stimulus.
  • History: The term history, refers to the environmental events other than the treatment that changes over time and may affect the scores in one treatment differently than in another treatment.
  • Instrumentation: Instrumentation refers to changes in a measuring instrument that occur over time.
  • Order effects: When an individual is tested in a series of treatment conditions, participation in one treatment may have an influence on the participants' scores in the treatments that follow and it is referred as order effects.
  • Maturation: Any systematic changes in participant's physiology or psychology that occur during a research study and affect the participants' scores are referred to as maturation.
  • Statistical regression: This refers to the tendency for extreme scores on any measurements to move towards the mean when the measurement procedure is repeated.
  • Interrupted time-series designs: Interrupted time series is a special type of time series where treatment/intervention occurred at a specific point and the series is broken up by the introduction of the intervention.
  • Single-case or single-subject designs: In the design of experiments, single-subject design or single-case research design is a research design most often used in the applied fields of psychology, education, and human behavior in which the subject serves as his/her own control, rather than using another individual/group.
  • Participant attrition or participant mortality: Participants frequently drop out of experiments whilst they are taking place/before they finish; something that is known as participant mortality or participant attrition.

Conclusion:

The terms defined above are needed to properly understand any statistical experiment.

Drug use The 2011 World Drug Report investigated theprevalence of drug use as a percentage of the populationaged 15 to 64. Data from 22 European countries are shown in the following scatterplot and regression analy-sis.

Besides the Regression analysis, spatial analysis, and time series analysis, explain an additional alternative approach to conducting the analysis for explanatory variables and response variables for Meaghan’s post below about a peer-reviewed scientific study that is a strong example of data collection: Meaghan’s Post: The below study was completed by conservationists to see and better understand the movement of a specific marine mammal species.  The study was done in the waterways of California. The subject is monitored using a random 1.8; mile movement. Results of this project are analyzed by scientists and researchers. The species is a very curious one which allowed for better care and gained interest before committing to it. Ten observation stations were used about 2.4 km per the intervals were measured at equal intervals throughout. This often feels very accurate because the evidence is supported by science and other similar publications that allow due to interact without being…
