Types of Variables | Road to Data Science 004

Have you ever wondered how companies predict your preferences, or how online platforms seem to know exactly what you're looking for? Well, that's not just magic—it's the fascinating world of data mining!

Variance is like the superhero that tells us how far each number in a data set is from the mean. It's the average of the squared differences from the mean. Meanwhile, Standard Deviation is like the sidekick—it's simply the square root of the variance.

There are three main measures of central tendency: the mean, the median, and the mode.

There are different types of measurement scales - Nominal, Ordinal, Interval, and Ratio

Categorical or numerical, discrete or continuous, or independent and dependent, understanding these concepts is like having the keys to unlock the secrets hidden in your data.
