Statistics for Teaching Science: Part 1 Measuring and Reporting Uncertainty
Statistics for Teaching Science: Part 1 Measuring and Reporting Uncertainty
All measurements include some degree of uncertainty or error, but how it is reported is decided by the person collecting the data. Because analysis is dependent on the data collected, the method used to report error can substantially impact the strength of the claims made and conclusions drawn. In this workshop, we will explore five […]

Statistics for Teaching Science: Part 2 The Problem with Describing Data Using the Mean
Statistics for Teaching Science: Part 2 The Problem with Describing Data Using the Mean
Often by middle school and certainly by high school, students default to the mean as the best way to describe data without much consideration for how they might defend that choice. So, you might think, what’s the harm in that? Everyone knows what is meant by this descriptor, it is familiar and understandable, easy to […]

Statistics for Teaching Science: Part 3 Getting Comfortable with Variance, Standard Deviation, Standard Error of the Mean, and the 95% Confidence Interval
Statistics for Teaching Science: Part 3 Getting Comfortable with Variance, Standard Deviation, Standard Error of the Mean, and the 95% Confidence Interval
The variance, standard deviation, and standard error of the mean are excellent methods for describing data because they convey the variability of the observed data around the mean. Anyone teaching AP, IB, Pre-AP, Pre-IB, or college-bound science students will likely want to know how to calculate these values, what they indicate, and how to contextualize […]
