Controlling for a variable

factors and the observed variables will be examined by Cronbach’s alpha (>.7; Nunnally,…

The variables used as search terms were: community policing, effectiveness, race/ethnicity, methods, results, comparisons, perceptions, trust views in the police, programs, Hispanic and others perception views on the police, and etc. Try to make the research as…

specify that some of the previous research does not control for certain confounding variables. In their study, the authors hope to reduce extraneous variability by “…controlling the number of recycling receptacles across conditions and by examining receptacle location without the use of posted signs” (712). The specific recyclable waste being measured was plastic water bottles.…

specifically look for causes and effects (Kovera,2010). It focuses only on whether there is a correlation between the x factors, y factors, and how strong that relationship is to the y variable output in your business process (Kovera,2010). In a scatter diagram that indicates a positive correlation of x and y variables, the data points fall to either side of a best-fit line that rises steadily from left to right (Summer, & Dehaney, 1943). In a scatter diagram that indicates a negative…

running a randomized-controlled trials simultaneously with randomly assigned control and test groups to capture the cause-and-effect relationship – if flat-fare option during different timing of the day is effective in increasing revenue. Controlling for extraneous variables, 2000 CD App users are randomly chosen as our target group. Using simple random sampling, 500 users from the target group are randomly chosen to form Control Group, Test Group 1, 2 and 3 respectively, and only users from the…

1. The hypothesis: Distractions during mealtimes is the reason for obesity and the increase of consuming unhealthy food. 2. The operational definition(s) of the dependent variable(s): There are two dependent variables in this research: the body mass index which was calculated according to the Center for Disease Control and Prevention Guidelines (CDC) and the food consumption. They have trained researchers to measure the height (cm) and also the weight (kg) of each participants. Body mass…

of the schoolchildren in Connecticut, in December of 2012. After this event the Obama administration began limiting the availability of military-style weapons and many policies have been established, placing many different variables on gun purchasing and owning. These variables range from background checks to gun safety classes. I believe that guns should be controlled. Citizens do have the right to bear arms, but I believe a citizen should prove that they are responsible enough to own a weapon.…

Focusing on US exports they find that political influence from CIA interventions were used to increase demand for US products in areas where there was a comparative disadvantage. In their study the independent variable is the level US government influence on other states and the dependent variable is the annual bilateral trade level between the US and said state. They measure international trade (using the gravity model) between the US and states in which the CIA has either installed a new…

Other variables include, the age of the child, the parent’s ability to control their aggression, as well as the direct connection between the child and their parents (relationship is a good or a bad one). (Oas, 2010) These particular variables are extremely important in understanding corporal punishment because when discussing proper ways to discipline a child, scholars have…

subjects sample. All protein measurements for the samples were normalized with Beta-Actin. Chi-squares were performed on categorical variables and ANOVAs were performed on continuous variables to test for differences across groups. Pearson Product-Moment correlations were used to examine preliminary relationships between protein levels and demographic and brain variables. Differences between groups were examined with repeated-measure ANCOVA with potential confounds being identified as; age, age…
