Document Summary
Foundations of statistics, describing variables, and focus on categorical variables. To use statistics one must consider the following: Formulate as precisely as possible your question of interest. Not a statistical question are violent crimes related to violent video games. Too vague, need a more discrete population of interest. Effective data presentation and description is a first step in most analyses. A lady at a shop insists on having a new tea because hers was made in the wrong order. If you told her to drink 100 cups, the experiment may change as the cups cool or subject gets tired. Make 4 cups of coffee and tell the lady that there are 2 cups of tea each prepared with the 2 different orders. Increases in unlikelihood is a matter of counting. Example: it was reported in the news that a young man who committed a robbery and murder at a convenience store was also known to play grand theft.
