The next step is to determine whether the p-value that results from the previous step is small enough that we are willing to reject the null hypothesis and conclude instead that the alternative is true.

Perhaps you decided to make coffee because it gives you a caffeine boost and helps you focus on the task at hand. So, if you start to feel anxious about the materials in your statistics course, remind yourself that other students in your class are likely feeling the same way and that the arousal could actually help you perform better, even if it doesn’t seem like it.

In this chapter, we will take a step back and critique “objectivity” and “value neutrality” that permeate the ideas in psychological research. We will also discuss their potential implications on research and practice when left unaddressed. Lastly, we will discuss the scientific reform movement and alternative frameworks of knowing.

Under this module, we can see how central limit theorem works by looking at different sources of distribution (e.g., normal, uniform, lognormal, etc.) and how the distribution of the sample means can lead to a normal distribution if the sample is large enough.

The variable editor can be opened by selecting “Setup” from the data tab or by double-clicking on the variable column header. The variable editor allows you to change the name of the variable and, for data variables, the variable type, the order of the levels, and the label displayed for each level.

The researchers asked Wansink to share the data from the studies but he refused, so they dug into his published papers and found a large number of inconsistencies and statistical problems in the papers.

However, it is important to note that it is not perfect as it often does not reflect the difficulty of the subjects that different students may have taken. We know that an ostrich, a robin and a chicken belong to the “bird category”, but we understand that these birds individually differ from one another.

The analysis can be removed by right-clicking on the analysis results to bring up a menu, and then selecting Analysis, and then Remove. To copy results right-click on the object of interest and from the menu select exactly what you want to copy. The menu allows you to choose to copy only the image or the entire analysis.
