Document Summary

Problem of variability: we act differently from one another. Problem of reactivity (demand characteristics): we act differently when we think that we are being observed. Science tools: measuring human thoughts and behaviours that give us precision and eliminate biases (operational definition, instruments, data, descriptive stat) Science rules: deciding what we observed that minimize the chance of biases and help us formulate theories (openness, falsifiable hypotheses, double-blind experiments, ethics) Objective measurements (operational definition): a description of a property in concrete, measurable ways (ex. Validity: measuring what it purports to measure. Power/sensitivity: detecting even very small differences in the measure. Descriptive statistics: set of mathematical tools that help us describe data. Central tendency: statistic that describes the data"s typical value. Variability: how different the data points are from one another (range, standard deviation) Ethics: data is acquired in a manner that is fair to the participants (data is not faked, plagiarized or altered)
