Statistics Program

The educational objectives of the Master of Science degree in Statistics are threefold: to provide professionally competent statisticians equipped to accept responsibilities in business, industry and public service positions, to provide the academic foundation needed to pursue the study of statistics at the doctoral level, and to provide opportunity for study of statistics at the graduate level by students whose primary area of specialization is a field in which applications of statistics are appropriate. (Such areas include social sciences, education, criminal justice and the physical sciences.)

Admission Requirements

Students seeking admission to the graduate program in statistics must meet the basic requirements of Graduate Studies specified in the ADMISSION section of this catalogue. In addition, the following are required:

1. A combined (V + Q + A) GRE score of at least 1500.
2. At least two letters of recommendation that address qualifications for graduate study.
3. For international students whose native language is not English, a TOEFL score of at least 600.

Graduate Minor in Statistics. Three specific plans are available for the graduate minor in Statistics with each plan requiring a minimum of 12 semester hours of statistics.

Plan I: Plan I is for graduate students seeking a minor in Mathematical Statistics. The required courses are STA 533, 561, 562, and 564 with STA 560 strongly recommended as well.

Plan II: Plan II is for students seeking the M.A. in Mathematics. The required coursework is STA 471, 472 or STA 561,562, and two additional courses selected from STA 533, 560, 566, 567, 568, 569, and 570.

Plan III: Plan III is for graduate students seeking a minor in Statistical Methods. This minor is particularly appropriate for graduate students in the social or natural sciences, education and criminal justice. The required courses are STA 533, 568, and 2 additional courses selected from STA 560, 566, 567, 569, and 570.
