Welcome to Basic Math for Data Analysis

[MUSIC]
0:00

Hi, my name is Megan and
I'm a teacher here at Treehouse.
0:09

My pronouns are she, her, hers.
0:14

In this course, I will refresh
your knowledge of some necessary
0:17

math skills that you will
need to be a data analyst.
0:22

A little stressed already?
0:25

Don't worry, I highly encourage
you to use a calculator or
0:27

your computer to do
the calculations in this course.
0:31

Performing calculations is one of
the primary uses of computers and
0:35

they are terrific at doing that.
0:40

We'll also take a look at how
to perform these using Python.
0:42

We're going to look at how
to calculate the minimum,
0:46

maximum, median, mean,
and mode of data sets.
0:51

These might be used to calculate
things like the average age of people
0:55

at a convention or the most common
favorite food listed on a survey.
0:59

We're also going to do a review of
percentages and the order of operations.
1:04

In this course, we'll do
the calculations manually first, and
1:09

then using Python to
produce the same results.
1:13

Let's dive in.
