In this video I explain external validity (or ecological validity) and criticisms of artificiality that can arise from laboratory experimentation. I also explain naturalistic observation and field experiments as ways of overcoming artificiality and collecting real-life data, though both of … Read More

Frequency Distributions, Normal Curves, and Skew

In this video I explain how a frequency distribution can create a visual representation of our data. I also describe a normal curve or “bell curve” and what it means for mean, median, and mode. Then I consider skewed distributions … Read More

Understanding Significance and P-values

In this video I explain the concept of significance and how it relates to both effect size, sample size, and the law of large numbers. The role of a p-value in describing the likelihood of data is explained with an … Read More
