They will not be told the study is about violence in such games else the children might alter their behavior if they knew the true nature of the study. Once the 36 students agree to be in the study‚ they will be randomly assigned to 3 groups (2 experimental groups and 1 control group)‚ each containing 6 males and 6 females. Computer generated random numbers will be used to make assignments. The three groups will be scheduled to meet separately at the school on three successive afternoons from 10:00am

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

If you were laying on your deathbed and there happened to be a cure for your disease‚ wouldn’t you want to have access to it? Even if the experimental drug was not 100 percent guaranteed to benefit you‚ at least you are giving yourself a chance to survive. On the other hand‚ it can be extremely difficult for clinical trial director’s to get the data that they need‚ without it being rather skewed. Generally‚ a clinical trial would not want to accept a patient who is terminally ill for the fact that
