For a class project in a statistics class you must collect data and then analyze it. You decide to collect data on how easily people could go one week without using various software/social media products. Specifically, you ask 60 of your fellow students which of the following 3 programs they would be most willing to NOT use for one week: e-mail, Facebook, or Twitter. You test to see if they prefer to go without one or the other.

A teacher of an art appreciation course wants to know if his course actually results in greater appreciation for the arts. On the first day of class, the teacher asks students to complete an art appreciation survey that assesses attitudes toward a variety of forms of art (e.g. Painting, theater, sculpture). The same survey was given on the last day of class. The teacher analyzes the survey data and found that scores were significantly higher on the last day of class than on the first day of class.

A psychologist is interested in the effects of social pressure on conformity behaviors. To investigate the phenomena, she has participants (n=100) first sit in a room alone and judge the length of a line. Then she has them sit with confederates who state that the line is much longer than it really is. After the confederates have made their estimates, the subject makes his/hers. The mean length given when they are alone is 5 with a standard deviation of 1.1. The mean length given when they are in a room with confederates is 7 with a standard deviation of 1.9.

A researcher wants to know if the number of hours taken during a semester and the number of hours worked each week has an effect on the grades a student receives. To test this, gets the GPA of 10 students who work more than 20 hours and are taking more than 12 credit hours, 10 who work more than 20 hours and are taking less than 12 credit hours, 10 who work less than 20 hours and are taking more than 12 credit hours, and 10 who work less than 20 hours and are taking less than 12 credit hours.

Abel and Kruger (2010) recently analyzed the smiles of professional baseball players listed in the Baseball Register. The photos of players were classified as either big smiles or not smiles. The age of death for all players was also recorded. The results revealed that players with big smiles (N=23) lived longer than those with no smiles (N=63). ____ would be the df if they used a t-test.

Twenty five students were identified as needing additional help with reading comprehension. These students took an extra class during the summer that specifically focused on understanding what they were reading in short stories, novels, and newspaper articles. After the summer long course, the students‘ average score was 70. The population scores are μ = 75 and σ = 10. The calculated statistic would be ______ .

An insurance company keeps careful records of how long all patients stay in the local hospital. Analysis of this data reveals that the average length of stay in the maternity ward for women who had a c-section is M = 3.9 days with a SD = 0.64. They analyze this to see how it compares with the national population data.

A psychologist is investigating cultural differences in emotional expression among small children. Three year olds (N=60) from six distinct cultural backgrounds are subjected to the same minor stressor (e.g., their parent leaves the room), and their emotional reactions are rated on a scale from 0 to 20. Df Between is ______

A researcher would like to determine whether the students at her university sleep more than most students. Suppose it is known that the number of hours college students sleep is normally distributed with a mean of 8. The researcher takes a sample of 144 students at her school and records the amount of sleep they get each night. It is found that they average 7.8 hours with a standard deviation of 1. The standard error is ___
What is 0.08? 1/sqrt144 = 1/12

A clinical psychologist wants to test the effects of exercise and meditation on moderate depression. Patients were randomly assigned to one of the following three treatment conditions: aerobic exercise, meditation, and reading inspirational books (control group). After two daily 30 minutes sessions of the assigned treatment over the course of a month, each person‘s level of depression was measured with a standard questionnaire to see if it changed from a baseline measurement.

The researchers recruited 40 drivers. Half of the drivers drove a high fidelity driving simulator after consuming a ―low dose of alcohol (i.e., 4-5 grams per 100/ml blood) and half had no alcohol. Additionally, half of the participants in each of these conditions had average driving experience (i.e., more than 50,000 km) and half had low driving experience (i.e., less than 50,000 km). The dependent variable was the drivers‘ reaction time to a stimulus presented in their peripheral vision. Obviously, longer reaction times indicate worse performance. Df for main effect of driving experience _____
What is 1?
