On this page, I will share codes on how to make fancy plots in R. I think that especially people working in the field of psychometrics/educational measurement and evaluation might reconsider data visualization. Here are some examples:
-
$\textcolor{#508AA1}{Line\ Graph\ 1}$ Türkiye versus G7 Countries {real data}
-
$\textcolor{#508AA1}{Line\ Graph\ 2}$ Türkiye versus EU Countries {real data}
-
$\textcolor{#508AA1}{Line\ Graph\ 3}$ Average Reading Achievement by Gender: Sweden {real data}
