This lower limit is known as the floor.

Floor effect definition. Floor effect basement effect. 1 a floor is the lowest acceptable limit as restricted by controlling parties usually involved in the management of corporations. The ceiling effect is observed when an independent variable no longer has an effect on a dependent variable or the level above which variance in an independent variable is no longer measurable. The specific application varies slightly in differentiating between two areas of use for this term.

The inability of a test to measure or discriminate below a certain point usually because its items are too difficult. In pharmacology a ceiling effect is the point at which an independent variable which is the variable being manipulated is no longer affecting the dependent variable which is the variable being measured. A ceiling effect can occur with questionnaires standardized tests or other measurements used in research studies. Psychology definition of floor effect.

There is very little variance because the floor of your test is too high. This is even more of a problem with multiple choice tests. In research a floor effect aka basement effect is when measurements of the dependent variable the variable exposed to the independent variable and then measured result in very low scores on the measurement scale. Usually this is because of inherent weaknesses in the measuring devices or the measurement scoring system.

In statistics and measurement theory an artificial lower limit on the value that a variable can attain causing the distribution of scores to be skewed. In statistics a floor effect also known as a basement effect arises when a data gathering instrument has a lower limit to the data values it can reliably specify. This could be hiding a possible effect of the independent variable the variable being manipulated. It essentially describes when the dependent variable has leveled.

Statistics definitions the floor effect is what happens when there is an artificial lower limit below which data levels can t be measured. Ceiling effect is used to describe a situation that occurs in both pharmacological and statistical research. In layperson terms your questions are too hard for the group you are testing. Floors can be established for a number of factors including.
