Document Summary

A finding may seem obvious after the face. We overestimate how accurate and skilled we: hindsight bias, overconfidence error are make predictions from a random series, mistakenly perceiving order in random events. Using science makes us objective and accurate. The measure is consistent across instruments and observers. Use of operational definitions helps with objectivity. Ultimately, researchers attempt to make conclusions about a population based on data collected from a sample. Population a larger group of people whose behaviour you"re trying to understand. Sample a subset of the population that you test in your study. Making sure that every individual in the population has an equal chance of being included in your sample who are most readily available: convenience sampling. Researcher biases when the researcher"s own expectations or theoretical slant can influence the study. Can control using a double-blind procedure: neither the researcher nor the participants know.
