trained examiner. Types of Variables: A variable is a state‚ condition‚ concept‚ or event whose value is free to vary within the population. An investigator may directly manipulate a particular variable in a controlled environment (frequency of brushing or type of tooth paste used) or study a nonmanipulated variable that occurs freely in a real world setting (age or malocclusion) in which the researcher merely selects them for inclusion in a study. The types of variables include: 1- Independent or

Experimental design is a research method in which researcher tries to examine causal effects by manipulating independent variable under controlled settings and measures whether it produces any change to the dependent variable. In an experiment experimenter deliberately imposes a treatment on a group of objects or subjects in the interest of observing the response. This differs from an observational study‚ which involves collecting and analyzing data without changing existing conditions. In an experimental

order to determine how lack of sleep effected their performance. Self-reported surveys on usual sleep cycles‚ academic records‚ and personal and demographic information were given at the beginning of the study in order to notice or eliminate extraneous variables. Our goal was to see if it was harder to retain information and then perform academically when deprived of sleep. Introduction Sleep deprivation has become a prominent issue in modern society. This problem can be due to many intrinsic

the independent variable. The second advantage of the experiment is the contamination of extraneous variables being controlled way more effectively in other designs. This allows researchers to isolate the variable and evaluate the impact. The third is the convenience and cost experimentation that are superior to other methods (McGraw-Hill Company). The benefit of this is that it allows experiment opportunities in scheduling data collection and the flexibility in adjusting the variables. The disadvantages

The dependent variable is the scores after taking the test with the different flavors. The control group was the test scores without any gum.Experimental group is the two different gum flavors (Spearmint and watermelon). The control variables are the location‚ the test each participant will take‚ and the brand of gum. The procedures of testing the gum flavors

that a variety of actions are automatically imitated‚ and that automatic imitation promotes social affiliation and rapport. We assessed the power of automatic imitation by comparing it with the strength of the tendency to obey verbal commands. In a Stroop interference paradigm‚ the stimuli were compatible‚ incompatible and neutral compounds of hand postures and verbal commands. When imitative responses were required‚ the impact of irrelevant action images on responding to words was greater than the
