👋 Hey guys! Today, we’re talking about central tendency and the three most common ways to describe a “typical” value in a distribution. It’s an essential concept in statistics that helps us understand data better. Let’s dive in!

**First, let’s discuss the three most common ways to describe central tendency.**

These are the **mean, median, and mode.** The mean is found by adding up all the observations and dividing by the number of observations. The median is found by listing the observations in order and finding the middle one. The mode is found by identifying the value that appears most often. 📈

**Now, let’s talk about what the mean and median describe about a distribution**.

Both the mean and median are ways of describing the **central tendency** of a distribution. The mean gives us an idea of what the “average” value is in the distribution, while the median gives us an idea of what the “middle” value is.

Since the median is the middle observation, half of the values in the distribution are above the median, and half are below. 🤓

- For example, let’s say we have a group of students, and we want to know their test scores. The test scores range from 60 to 100, but what’s a typical score? We could find the mean or median score, which would give us a good idea of what a typical score is. If the median score is 80, that means half of the students scored 80 or above.

So there you have it! 🎉 Central tendency is an important concept in statistics, and the mean, median, and mode are the three most common ways to describe a “typical” value in a distribution. Keep learning, guys! 👨🎓👩🎓
