WPC 300 – Mid Term Exam Study Guide
Discuss what makes analytics science
o Defining characteristics of science – Questioning, Exploring, Observing, Comparing,
Measuring, Experimenting, Discovering.
o Facts (evidence) – Irrefutable piece of information. Not an opinion.
o Falsification
o Parsimony – Preferring the simpler answer over the more complicated in-depth answer.
o Etc.
Different analytical modeling techniques, be able to understand what is the best analytical
technique for different business scenarios.
o Descriptive – Why, How, When, did this happen? Based on the past.
o Predictive – Predicting what will happen based on what happened in the past.
o Explanatory – Explaining why something occurred.
o Prescriptive – Recommending action. Using all techniques.
Be able to design an experiment given a scenario
o Golden standard – Randomized Double-Blind.
o What does randomization mean? – Equal Chance.
o Control group, treatment group – Control group, left alone and observed. Treatment group,
intervened with.
o Outcome measures – Our results.
o A/B testing – Comparing two or more groups
Given a scenario, discuss to experiment or to observe.
o Explain limitations of observations – Subject to confounding variables.
o Explain strength of observations – Long periods of time. Ample amount of data. Easier.
o Explain limitations of experiments – Harder to construct. Expensive. Short.
o Explain strength of experiments – Clear data. Able to determine causation. Limits the
possibilities of confounding variables.
Understand sampling from population
o Why sampling – Not practical to study the WHOLE population. Sampling is more feasible
with time and resources.
o Sampling methods – Convenience sampling. Random sampling. Cluster sampling.
o Sources of sampling biases – Response and non-response bias. How the questions is phrased.
o Be able to discuss potential sampling biases given a scenario -
Understand group comparisons
o Understand the concept of statistical significance -
o Understand t values and p values -
o Be able to compute t values -
Cluster analysis
