Visualization & Pearson’s correlation coefficient The 30DayChartChallenge is a data visualization community that hosts daily challenges for April. Today’s challenge involves dinosaurs. I used the Datasaurus package to create an animated visualization to demonstrate the importance of graphing data, and the effects of outliers on statistical properties.

Lissajous Curves Lissajous curves are created by plotting two oscillations on perpendicular axes and ​​​. These oscillations, represented by sinusoidal functions, intersect to create different patterns. When the ratio of these frequencies is equal to — the oscillations are equally phased— the curve is a straight line.

TL; DR: Don’t be an absolutist– use relative paths. Use the here package instead of setwd() or getwd() to increase reproducibility and avoid wasting your and other people’s time.

RQ: What exactly is the CLT and what’s the deal with n 30? CLT - mathematical definition and simple terms definition How we use CLT How to know when empirical distribution converges to normal distribution? How did we come up with n $ $ 30? Cohen (1991) Taught that at least 30 observations were needed to use critical-ratio approach used in t-tables when comparing groups.

Quantile Beta Regression The quantile beta regression model discussed in the 2021 paper by Running Code When you click the Render button a document will be generated that includes both content and the output of embedded code.
