You are interested in understanding the central tendency and variance within your class' test scores, so you randomly collect a sample of 15 test scores from your peers. The test was measured on a scale from 0-100. Consider the following dataset for the following questions: 78 64 91 82 98 73 89 93 85 Reporting the Central Tendency: 1. What is the Mean for this dataset? 2. What is the mode for this dataset? 3. What is the Median for this dataset? 839 5. What is the variance for this data? 87 6. What is the standard deviation for this dataset? 62 88 4. What measure of central tendency would you use to report these data in a report? 94 91 100 Reporting Variance (Show your work on the back of this paper for the next two questions): You are interested in understanding the central tendency and variance within your class' test scores, so you randomly collect a sample of 15 test scores from your peers.
