A great place to start building a solid foundation! This course introduces you to basic concepts in quantitative social science studies. Topics include:
This course examines how we can apply the basic statistical building blocks, measures of central tendency and variance, to data samples in order to draw inferences about larger populations. Topics include:
Let's take a closer look in order to fill in the missing gaps! Topics include:
This course uses a task-based approach to developing R programming skills. No programming experience necessary.
What good are statistical models if you can't trust your data? This course discusses the concept of measurement -- what it is and what it isn't. Various factor analytic and Rasch measurement models are introduced, as well as how to apply them to real data in the R programming environment.
An introduction to how you can share your R analyses online. A focus on creating interactive dashboards and web apps. Specific tools that are introduced:
Data Science aims to solve real-world problems using quantitative datasets. It incorporates statistics, research methods, and computer programming.
An introduction to collecting and exploring data, statistical inference and hypothesis testing, building and testing models, machine learning, and presenting research
findings. This course takes a constructivist approach where students are challenged
to integrate the scientific concepts and statistical tools presented in class into a
critical research article on the topic of their choice. Students are encouraged to
decide for themselves how content is applicable for investigating their specific research questions and sharing their results in a convincing way. Weekly guidance
will be provided by the instructors as well as classmates. Students are holistically
assessed on the effectiveness of their final analysis, the extent to they communicate
the discoveries and challenges of the research process in a series of blog posts, and
their participation in the class and R programming lab sessions.
Do you use the internet every day for your job and personal life yet have no idea how it works. Does this make you uncomfortable? If so, this is the course for you!
