Statistical Reasoning in Psychology

Research and Statistics in Psychology Research and Statistics play an important role in psychology. Researchers in the field of psychology study what people will do or how they will react in any situation. Since not everyone reacts the same to a certain situation, statistics is used to see if a certain action happens often enough to come to an idea about cause and effect. It used to be believed that statistics could prove anything (Helberg). This is not true. It would only be found true if the researcher used statistics improperly and tried to bend the rules to validate their view on the subject matter (Helberg). Research and Statistics have many different areas that prove important for psychology.

Statistics Statistics refers to techniques and procedures for analyzing and interpreting data, displaying data and decisions made based on the data collected. In Statistics there are different areas to be able to find and explain certain types of things being researched. There is inferential statistics, descriptive statistics, variables, parameters, summation notation and measurement scales. Statistics which is often considered confusing can be cleared up with explanation and examples of each area. Descriptive Statistics is a summary of the collected data. It helps to organize it in a way that makes it understandable. An example would be: A personality test on 1000 college students that measures how out going they are. There are two ways that the results can be put together. A numerical graph computes the mean and standard deviation by showing the average degree of outgoingness and the degree in which they are all different. Graphs such as the stem and leaf display and a box plot would show detailed information about those studied and the scores of the different…...

...Name PSY 315 Week 5 Practice Problems Chapter 7: 14. Evolutionary theories often emphasize that humans have adapted to their physical environment. One such theory hypothesizes that people should spontaneously follow a 24-hour cycle of sleeping and waking—even if they are not exposed to the usual pattern of sunlight. To test this notion, eight paid volunteers were placed (individually) in a room in which there was no light from the outside and no clocks or other indications of time. They could turn the lights on and off as they wished. After a month in the room, each individual tended to develop a steady cycle. Their cycles at the end of the study were as follows: 25, 27, 25, 23, 24, 25, 26, and 25. Using the .05 level of significance, what should we conclude about the theory that 24 hours is the natural cycle? (That is, does the average cycle length under these conditions differ significantly from 24 hours?) (a) Use the steps of hypothesis testing. (b) Sketch the distributions involved. (c) Explain your answer to someone who has never taken a course in statistics. Step 1: H0: M=24 (Null) H1: M 24 (Alternative) Step 2: X | | | 25 | 0 | 0 | 27 | 2 | 4 | 25 | 0 | 0 | 23 | -2 | 4 | 24 | -1 | 1 | 25 | 0 | 0 | 26 | 1 | 1 | 25 | 0 | 0 | x= 200 S2 =10/7= 1.42857 S2m= S2/n=10 7/8= 0.17857 Sm=Sm2= 0.422577 Step 3: (=.025, DF=7) =2.365...

...Basic Concepts in Positive Psychology Stuart Zarahn PSY/220 Alan Coffin 05/29/2015 Researchers refer to’ Subjective Well- Being’ as how people experience the quality of their lives, and includes both emotional and cognitive judgements. They have defined ‘happiness’ as a combination of life’s satisfactions and how frequently we experience positive and negative effects. SWB includes our mood swings and emotions, as well as an overall satisfaction of our lives. Basically, subjective well-being is the positive and negative things that happen to us, how frequently they occur, the importance as they pertain to our happiness or sadness, and are linked to our personality traits. Everyone responds in their own way to a crisis or to a joyful event, so how and why we respond depends upon our personalities. John Lennon said it best, “Life is what happens to you while you’re busy making other plans” As far as being hooked up to a feel great all the time machine, if it was temporary like the “orgasmatron” in Woody Allen’s movie, or having a tube in my mouth that was attached to a tank of nitrous oxide (reality for me in 1970), then sure, why not? If it is a permanent situation, then no thank you. I might as well be in a catatonic state, feeling no emotions, pain, or joy, disconnected from reality or in a coma. All social interactions would be gone as I sat there with a perpetual stupid grin. I knew a girl named ‘Frankie’ who dropped a lot of LSD back in the late 60’s, early......
