Variables - any factor that can change in amount or kind over time. Eg age‚ time‚ IQ‚ memory etc An experiment tests the cause-effect relationship between variables Independent variable – the variable that is systematically manipulated‚ changed or varied in some way by the experimenter‚ in order to assess its effect on participant’s responses (DV) Dependent variable – the variable that the experimenter is measuring‚ shows any effects of the IV It is called the DV because whether or not it will

and The Bureau of Justice web site. The model is: CRIME = UNEMP+CPI 2. Definition of Variables The dependent variable is defined as the Crime Rate (CRIME). This will take into account the annual rate of both violent and property crimes committed during a measurable time period‚ of 1970 to 2001. The independent variables are: • UNEMP (Unemployment Rate) This variable was chosen because when the lack of available opportunity exists to provide income and the means

improves memory‚ to determine the flaws in her experiment. In the process‚ the paper also clearly explains the various key factors which determine the outcome and accuracy of the method of experimental research‚ such as dependent variables‚ independent variables‚ experimental groups‚ and control groups. This paper examines the factors that render Professor Smith’s experiment as flawed‚ and finally attempts to redesign an experiment to successfully test the effects of Vitamin E on memory

hypothesis statements. A research hypothesis is a statement about two variables‚ independent and dependent‚ and their relationship with an expected outcome based on the research question which‚ if directional‚ will state the expected direction of the relationship between the independent and dependent variables. If the research hypothesis is nondirectional it will not state the expected direction within the relationship of the variables but that a relationship exists. The statistical hypothesis or null

Probability distribution of the stochastic part of the model Upper range=Average X+ (95%)*standard error Standard error= coefficient/t-statistic Spurious regression:independent variables can appear to be more significant than they actually are if they have the same underlying trend as the dependent variable.

Abstract Introduction The Pearl River Delta has been a prosperous industrial area as many other areas in China in the last 3 decades. Although there is still growing demand for garment products the competition between factories has become fierce and factories will go the extra mile to keep clients’ satisfaction and deliver goods on time. Apart of the competition between factories‚ there are other threats which are making the Pearl River Delta less attractive for apparel firms. (a) The

Sixties as a purely empirical proposition to explain bilateral trade flow. The data was taken from the SAARC countries to evaluate the factors affecting the bilateral trade. The variables that impact on bilateral trade are studied in this report‚ as in: GDP and distance are independent variables and trade flow as a dependent variable. Export of Pakistan is found to be sig with Afghanistan‚ Bangladesh‚ India‚ Maldives and Srilanka and insignificant with Nepal and Bhutan. Import of Pakistan is found to be
