DPH 623, Biostatistics I class has 10 students. The instructor surveyed the birth month during the class. The following is the raw data which has also the instructor’s birth month. So, the number of total sample is 11.
7, 12, 11, 9, 11, 6, 3, 8, 12, 12, 8
If you draw the Box plot of these data, which of the following is right about the shape?
| Right skewed |
| Bimodal |
| Left skewed |
| Symmetric |

Unit 6 Lesson 3 Classwork (Adapted from Math Vision Project) Data Distribution A lot of information can be obtained from looking at data plots and their distributions. It is important when describing data that we use context to communicate the shape, center, and spread. Shape and spread: Modes: uniform (evenly spread- no obvious mode), unimodal (one main peak), bimodal (two main peaks), or multimodal (multiple locations where the data is relatively higher than others). Skewed distribution: when most data is...

8. A student scores 56 on a geography test and 285 on a mathematics test. The geography test has a mean of 80 and a standard deviation of 20. The mathematics test has a mean of 300 and a standard deviation of 10. If the data for both tests are normally distributed, on which test did the student score better relative to the other students in each class? (You must show proper work to receive credit on this problem) 9....

Graduate Programs in Statistics! One of the many wonderful things about studying statistics is that graduate programs in statistics often pay their graduate students, which means that many graduate students in statistics are able to attend graduate school tuition free with an assistantship or fellowship. In 2009, there were 82 US statistics or biostatistics doctoral programs for which enrollment data were available. The dataset Statistics PhD lists all these schools together with the total enrollment of full-time graduate students in...
