Examples of Sampling Bias and Demand Characteristics through a Daily Show Clip

A clip (5:30) from the The Daily Show with Jon Stewart that demonstrates how sampling bias and demand characteristics can lead to misleading conclusions. “Poll Bearers: Cable news polls might not reflect public opinion so much as the ability of viewers to repeat the ideas they just heard.” View the episode here.

First Day Getting to Know You Survey

Establishing a rapport with students is connected to students’ success, interest, and pro-academic behaviors. Rapport can be particularly hard to establish in an online learning environment. One way to help establish rapport is by starting the semester with a survey that helps you get to know the students and their needs. Teachers who do this …

Video: Independent-Samples t-test (SPSS for Beginners)

Video (8:11) from Research by Design and Dr. Todd Daniel, described as follows, “Another way of measuring the difference between two samples is to compare two unrelated groups or participants or samples. In this design, you measure two groups one time; in contrast, the previous paired test measured the same sample two times. With independent …

Video: One Sample and Paired-Samples t-test (SPSS for Beginners)

Video (6:02) from Research by Design and Dr. Todd Daniel, described as follows, “When we calculate the mean of a sample, we can then use a one-sample t test to compare that sample mean to another mean, such as a mean from a population, a normative group, or another known value (mean). The “one sample” …

Video: Correlation (SPSS for Beginners)

Video (9:52) from Research by Design and Dr. Todd Daniel, described as follows, “Using the dataset we created in the first video, we now explore the relationship between our two scale-level variables: height and weight. We will use Pearson’s correlation to measure this relationship. We will also learn about a point biserial correlation with gender.” …

Video: Random Sampling

A brief (2:25) video from Pew Research Center in which, “The first video in Pew Research Center’s Methods 101 series helps explain random sampling – a concept that lies at the heart of all probability-based survey research – and why it’s important.”

Video: How to Do Chi-Square in JASP

Video (10:27) from Research by Design in which, “We learn how to calculate a One-Way Chi-Square goodness of fit test in JASP using the setting for Multinomial Test. For the null hypothesis, we assume that the observed values in one group (the Pigs) do not differ from the values in a comparison population (the Bears) …

Video: How to Do Simple Linear Regression in JAS

Video (23:18) from Research by Design in which, “Exploring our data about burnout and job satisfaction, we predict an outcome with a single variable using simple linear regression in JASP. I explain how regression works, then open an SPSS dataset in JASP. We explore the assumptions of homoscedasticity and linearity with a scatterplot and normality …
