Experimental studies manipulate factors to determine their effects.
An experimental study involves manipulating one variable (called an independent variable) to determine its effect on another variable (a dependent variable). An example of a manipulated variable (independent variable) can be hours of sleep, and the dependent variable (resulting variable) can be speed of reflexes. Hours of sleep (independent variable) can be manipulated (increased or decreased) to see the result it has on speed of reflexes (outcome or dependent variable).
The answer is B. to control all laws in each state. I think. :3
Whenever a research is done, you must reject or accept a null hypothesis (the one you consider is not correct) or your work hypothesis (the theory you think is must probably accurate or close to the truth) usually, when performing a research, you will not always obtain positive or statistically significant results, that validate your hypothesis. Is actually, not unusual that extremes (or extraordinary results) come out (unexpected for several reasons: incorrect size of the sample, improper selection of the subjects- a bias- lack of correct determination of the variable measured or failure to determine the type of the variable-numerical, categorical, ratio,etc-)
Positive or negative results are yet, results whether they prove or reject your hypothesis. Failing to establish a scientific hypothesis does not necessarily mean that they did something wrong, it just says that the hypothesis tested does not approach correctly to the epistemological truth (ultimately, any research is only a mere approximation to reality). Therefore, when two scientists deny sharing<em> unusual results</em>, they are acting unethically, hiding results that can mean something from a different point of view.

Answer:
On the Wechsler Adult Intelligence Scale (WAIS), the <u>verbal</u> score represents subtest scores on verbal tasks, such as vocabulary, comprehension, and general knowledge; the <u>performance</u> score represents subtest scores on nonverbal tasks, such as identifying missing parts in incomplete pictures, arranging pictures to tell a story, or arranging blocks to match a pattern.
Explanation:
WAIS is an Intelligence test who has different subtests to measure both verbal and non verbal performance. The intention of ths scale of intelligence is to calculate the intelligence quiotient. Also to analyze whether the person has specif problems in a particular area.
