LEVEL 200, 300 and 400 COURSES

ACTU  202:Data Analysis and Statistical Computing

To acquaint students with elementary modern computing methods appropriate to the work of an actuary. This course is largely practical and involves analyzing large data sets. Students will be introduced to modeling and statistical simulations using modern statistical software such as R. Exploratory Data Analysis and Confirmatory Data Analysis of both univariate and bivariate cases will be explored. Applications will be tailored to meet requirements of the Actuarial profession with hands-on training sessions with large data sets. No ‘new’ statistical methods should be presented but interesting data can be analyzed using known methods on the chosen package. Topics should include graphics, descriptive statistics, representations of multivariate data, simple hypothesis tests, analysis of variance, and linear regression.

ACTU 320:Internship in Actuarial Science

Aim: The core aim of this course is to introduce students to the Actuarial practices in jobs that they find themselves in. This in turn will bridge the gap between theory and practice. The course is offered in both semesters to students to seek practical applications of actuarial principles in insurance companies, financial institutions, pension consulting firms, and other related fields. The course requires students to participate in an internship program within the industry. Students need to submit monthly progress reports and a final semester report to the Head, Department of Statistics, University of Ghana, Legon.
