1. Describe the study design (is it correlational, experimental, survey research, etc.). The study is Level 3, experimental. The participants are within subject design experiences because since the subjects were divided into two groups by gender.

In this experiment, we performed this experiment twice (1st and 2nd rounds) over approximately five month. Twelve male

Will you be using a between-subjects or within-subjects design? If you have more than one IV, you need to answer this question separately for each IV. I will be using within subjects design. The participants will be given the same treatment during the experiment.

A simple probability is demonstrated by first creating a pivot table with correct values. A pivot table was created using the Student Data File eliminating insignificant table fields. The pivot table consisted of two genders, Male and Female categorized as Event A on the Possibility Calculations Excel Sheet. Each gender elected a major which contained the following categories: Marketing, finance, leadership, and no major; labeled as Event B on the Probabilities Calculation Excel Sheet.

Unit 2 Assignment: Diagnostic Writer’s Response Whether it is a little or a lot, everyone experiences stress at some point. Stress does not always have a negative effect, most of the time the effects can be positive. On the other hand stress is associated with the development of most major mental health problems such as depression, Posttraumatic Stress Disorder (PTSD), and pathological aging (Marin, 2011). It has also been linked to all leading physical causes of death such as heart disease, cancer and stroke (Cohen, Janicki-Deverts, & Miller, 2007).

a biology class wants to perform an experiment to investigate the effect of different colors of light of green, yellow, red and clear cellophane and plant three seeds in each one. What part do the three seeds experiment? A,Confounding variables B.Independent variables C.Control variables D.Dependent variables 40. Iodine directly helps which of the following glands to function properly?

Dr. Doodley hypothesized that fast music would enhance people’s work performance. To test her hypothesis, she chose two different secretarial pools and chose to control what speed of music they would be working with, making that the independent variable, while the dependent variable is the performance of the groups based on the type of music they listened to while working. Based on the experiment’s purpose, the experimental group is the pool exposed to fast music. In which case, the control group would be the pool exposed to slow music. The control group used for the experiment was not appropriate, because there was a malfunction with the tape.

The subjects must be placed in appropriate conditions, with equal treatment, and with the use of a proper control experiment.

Through the ins and outs of this experiment, the goal was to see if hanging a chicken feeder on a hook decreased the amount of chicken feed that was consumed by birds. The question that was asked was “If a chicken feeder is hung off of a hook, then will the amount of chicken feed eaten by wild birds decrease?”, and the hypothesis is “if a chicken feeder is hung off of a hook then the amount of chicken feed eaten by wild birds decrease”. There were numerous variables and trials that had to take place for the experiment to perform as desired. The control group was the feeder that was at ground level, and this portion of the trial was tested seven times. The experimental group was the feeder that was not at ground level, but on a hook.

Stanley Milgram wants to know how people would go in obeying an instruction. For his experiment he stand a procedure it is different from others. His experiment taken at human beings. 40 males aged between 20 and 50 were selected for the experiment, These 40 males were professionals who is unskilled. There is a teacher and learner in his experiment.

In this particular experiment the constant condition, the factor that was never changed, was the room temperature water. The independent variable, the variable the student affected, was how much water was placed into the beakers. The dependent variable, a variable that was affected by the independent variable, was the time it took for the tablet to fully dissolve. The control group, which did not receive treatment from the students, was the 50 ml of water as a result of being the medium between the three measurements of water. Finally, the experimental group, the subject that was exposed to the variable during the experiment, was the 25 ml and 75 ml of

The other being how perceptions of other races change after having or not having an interracial room during the first year of college. The study was a natural field experiment. Whereas in a lab, conducting field research allowed to follow long term interactions. There was no need for manipulation and random assignment was guaranteed by how the school assigned housing to freshmen, which served as the independent variable.

Specific purpose: To inform my audience the physical, mental, and emotional effects of stress. Central Idea: Stress effects people physically, mentally, and emotionally. Introduction I. Imagine being so stressed that it affected you emotionally, physically, and mentally. II.

The things that went well in the experiment are the experimentation portion of the experiment. The problem we had completing the project was making sure that the test was fair for the people that

3. Review of literature 3.1 Stress and its types: Stress is an essential mediator of human behaviour. Immediate physiological response to any type of stressor facilitates survival of the species at its maximum. Despite of normal homeostatic regulatory mechanism, the stress responses can become maladaptive. Chronic stress, for example immobilization, exposure to noise, irradiations, psychological stress can leads to a host of adverse health consequences, including cardiovascular diseases, neurodegeneration, obesity, depression and early ageing (McEwen et al, 2004).
