STAT 230 Learning Objectives
Every person in the current society will need a basic understanding of data analysis and statistical concepts, to become able to think critically regarding the quantitative information we come across every day, by opinion polls to topic news information based on scientific studies. We need to be able to understand the details that is being presented and also to ask the proper questions about any results that are sucked from it.
STAT 220 has no formal math prerequisites, although high school algebra is assumed. Required numeracy skills consist of: fractions, percentages, square roots, exponents, and equation of any line. Virtually any particular 1 / 4 there may be small deviations using this list of goals. After completing this program, students are able to:
вЂў Clarify and apply principles of study style and data collection. o Identify the kind of population, test, study units (subjects), variables, and factors;
o Separate observational studies and managed experiments; u Describe the impacts of study design and style on the ensuing generality of conclusions that may be draw;
o Recognize examine designs that do/not enable conclusions about causation; to Describe what sort of study could possibly be changed to allow conclusions about causation; o Describe simple sampling strategies (simple random sampling, stratified sampling, census versus sample), their strengths and weaknesses;
o Identify sources of potential bias in study styles and strategies for reducing individuals biases. Problems include sample and nonsampling bias, confounding, lurking factors, spuriousness, record control;
um Identify concerns of values in analyze designs;
o Describe the impact of randomization in analyze design.
Produce and interpret visual summaries of data.
o Histograms, stem-and-leaf layouts, and scatterplots;
o Recognize qualitative vs quantitative data and the relevant data displays for each;
o Based on graphical displays, identify basic...
