Please answer questions E-H 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.1 The dataset Statistics Grad Schools lists all these schools together with the total enrollment of full-time graduate students in each program in 2009.Click here to access StatKey.1Full list of the 82 Group IV departments was obtained at http://www.ams.org/profession/data/annual-survey/group_iv. Data on enrollment obtained primarily from Assistantships and Graduate Fellowships in the Mathematical Sciences, 2009, American Mathematical Society. The list does not include combined departments of mathematics and statistics and does not include…

1. In statistics the term frequency is normally thrown around, especially relating to tables and charts. Explain the term frequency in statistics as well as the concept of cumulative frequency. 2. As mentioned above, tables and charts are used to illustrate data in statistics. Some of the common tables and charts used are tally charts, cumulative frequency table, bar/ column chart, histogram and pie chart. 3. Using these numbers 17 17 19 12 13 16 17 14 14 11 14 17 18 16 14 14 17 13 18 19 18 14 12 19 17 11 19 13 15 17 15 15 17 12 17 13 16 12 16 13 13 11 12 11 16 13 15 16 13 13 Example Class 11 12 13 14 15 16 a.
