Document Summary
Five characteristics of quality scientific research: it is based on measurements that are objective, valid, and reliable, it is be generalized, it uses techniques that reduce bias, it is made public, it can be replicated. The foundation of scientific methodology is the use of objective measurements, the measure of an entity of behavior that, within an allowed margin of error, is consistent across instruments and observers. For example, weight is measured in pounds or kilograms. Your weight will be the same regardless of whether you"re using the scale in your bathroom or the scale in the change room at the gym. However, the weight will vary slightly from scale to scale, this is the margin of error mentioned in the definition. Weight would be considered a variable, the object, concept, or event being measured. Operational definitions are statements that describe the procedures and specific measures that are used to record observations.
