Misconception: Statistics is only for numbers

Population parameters describe the entire population, while sample parameters describe a subset of the population.

Statistics encompasses more than just numerical data; it also involves categorical and categorical-ordinal data.

The choice of statistical test depends on the type of data and the research question. For example, if you're comparing means, a t-test is often used.

Statistics and probability are branches of mathematics that deal with the collection, analysis, and interpretation of data. Statistics focuses on the methods used to collect and analyze data, while probability deals with the chance of events occurring. Think of statistics as the process of gathering data, and probability as the tool used to make sense of that data. For instance, if you flip a coin, the probability of it landing heads-up is 50%. Statistics would help you gather data on the number of times the coin lands heads-up, while probability would enable you to calculate the likelihood of this happening in the future.
