STAT 1450 Study Guide - Final Guide: Standard Deviation, Bird Control, Central Limit Theorem
Document Summary
Stat 145 final exam review - solutions: music and studying, who 62 people. What type of music and number of objects remembered correctly. Why researchers hoped to determine whether or not music affects memorization ability. How data were gathered in a completely randomized experiment: type of music (rap, mozart, or none) is a categorical variable. Number of items remembered is a quantitative variable: mozart and rap had very similar distributions of the number of objects remembered. The scores for none are, if anything, slightly higher than the other two groups. Generally, students who scored high on midterm1 also tended to score high on. According to the model, a student with a midterm1 score of. 80 is expected to have a midterm2 score of about 82. This is a reasonable prediction, since our x is in the range of the data: we can make predictions for any midterm1 score between about 65 and 97.
