A study was designed to compare the attitudes of two groups of nursing students towards computers. Group 1 had previously taken a statistical methods course that involved significant computer interaction. Group 2 had taken a statistic methods course that did not use computers. The students' attitudes were measured by administering the Computer Anxiety Rating Scale (CARS). A random sample of 16 nursing students from Group 1 resulted in a mean score of 59.2 with a standard deviation of 33. A...

Depressed patients were randomly assigned to one of three groups: a placebo group, a group that received a moderate dose of the drug, and a group that received a high dose of the drug. After four weeks of treatment, the patients completed the Beck Depression Inventory. The higher the score, the more depressed the patient. We are now also interested if a patient's weight has an effect on the drug's effectiveness. Patients were categorized as either underweight, overweight, or 'medium...

Sometimes the extent to which two groups differ is quite obvious. For example, if one group of individuals has an average of 20 speeding tickets, while another group has an average of 2, we can be pretty sure that the difference is statistically significant. But sometimes it is less clear. What if one group had an average of 10, while the other had an average of 7? T-tests provide a way to determine if differences between means are enough to...
