The Floor Effect Explained

Let s talk about floor and ceiling effects for a minute.

The floor effect explained. This lower limit is known as the floor. An interest rate floor is an agreed upon rate in the lower range of rates associated with a floating rate loan product. Plate tectonics theory dealing with the dynamics of earth s outer shell that revolutionized earth sciences by providing a uniform context for understanding mountain building processes volcanoes and earthquakes as well as the evolution of earth s surface and reconstructing its past continents and oceans. This could be hiding a possible effect of the independent variable the variable being manipulated.

In layperson terms your questions are too hard for the group you are testing. This is even more of a problem with multiple choice tests. Learn what a ceiling effect is and how to eliminate it using the overall experience rating developed and. Common scales used in visitor studies and evaluation often suffer from ceiling effects.

A floor effect is when most of your subjects score near the bottom. Limited variability in the data gathered on one variable may reduce the power of statistics on correlations between that variable and another variable. 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. There is very little variance because the floor of your test is too high.
