Catalog Course Description: A general education course in statistics that is useful for all majors in the behavioral and life sciences. Students are introduced to principles and procedures of measurement, data base management, data analysis, probability, sampling theory and statistical significance. The course covers Descriptive Statistics: measurement scales, frequency distributions, measures of central tendency, measures of variability, measures of linear relationships, standard scores; and Inferential Statistics: logic of hypothesis testing, z-tests, independent-samples and dependent-samples t-tests, one way analysis of variance, correlation procedures, and non-parametric statistics. In addition, a conceptual introduction of two-way analysis of variance is covered in this course.
Prerequisite: Intermediate algebra
BA Program Core Purposes:
Critical and Creative Thinking are the necessary thought processes of an effective thinker who uses divergent and convergent thought patterns to arrive at an appropriate conclusion in a given situation. This objective cultivates students’ skills in reaching conclusions founded on their examination of a variety of authorities within and across various disciplines and with engaging in innovation and risk taking.
Effective Communication is the co-creation of meaning focusing on how people use content to generate understanding within and across various contexts, cultures, channels, and media. It always includes a communicator, an audience, a subject, and a situation. Effective communicators create a purposeful message designed to increase knowledge, to foster understanding, or to promote change in the listeners’ attitudes, values, beliefs, or behaviors.
Global and Intercultural Awareness is a collection of skills that promote effective interaction in a variety of cultural contexts. Global awareness is an understanding of the interconnections between nations, socio-cultural groups, individuals, and the elements that influence them. Intercultural awareness is knowledge of and sensitivity to diversity in all its forms, and a variety of factors that shape culture including worldview, communication, cultural rules, and personal biases.
Holistic Personal Development is the multifaceted process of becoming self-actualized. It involves all aspects of the self–including the physical, mental, emotional and spiritual–and includes taking personal responsibility for one’s own learning and development through a process of assessment, reflection, and action.
Competence for Professional Pursuits is an understanding and a disposition that a student builds across the curriculum and co-curriculum, from making simple connections among ideas and experiences to synthesizing and transferring learning to new, complex situations beyond the classroom into a professional field. Students explore the central knowledge, skills, and professional conduct of their chosen field or profession to prepare for engagement in meaningful and socially responsible work.
Praxis for Social Justice combines learning and doing for the purpose of encouraging critical consciousness, ethical reasoning, and socially responsible behavior through civic engagement. This objective advances critical awareness of the social, economic, political, and environmental justice issues that demarcate the terrain of power, oppression, and resistance. Praxis for social justice includes developing the commitment, skills, and knowledge necessary to contribute to the on-going work for justice through activism and engagement that embraces local and global communities.
- Identify and distinguish the four kinds of measurement scales used in assigning numbers/values to variables.
