Greetings, data enthusiast! Today, we're diving into descriptive statistics using R
. We'll explore measures of centrality — the mean, median, and mode — using R
's built-in functionalities.
Central tendency finds a 'typical' value in a dataset. Our three components — the mean (average), median (mid-point), and mode (most frequently occurring) — each offer a unique perspective on centrality. The mean
indicates average performance when decoding students' scores, while the median
represents the performance of the middle student, and the mode
illuminates the most common score.
This plot depicts the mean
of a given dataset or its centered location, also considered the 'average'. Imagine a seesaw balanced at its center - the mean
of a dataset is where it finds balance. As a crucial statistical concept, it visually expresses where most of our data is centered or skewed.
