1Starting your Data Analyst Journey

Your journey to becoming a data analyst will start by understanding more about data and the analysis thereof. This lesson is geared to help you understand why data analysis is an important skill as well as where it can be used to enhance your business making decisions. Each one of our lessons is carefully balanced between theory and practical and in this lesson, you can expect to learn how to import and clean data using a variety of methods and tools. We will focus on logical checks to help guide you towards thinking about data in a more logical fashion.

2Exploring Data

In this lesson, we will understand the data in a bit more detail. The aim is to assist you in understanding the different data types (such as categorical vs numerical) as well as understanding graphically represented data. You will also learn how to describe data (i.e. descriptive statistics) and how to implement descriptive statistics "features" in data.

3Probability

As our journey continues, you will learn how to install the Data Analysis Toolpak together with some descriptive stats. We will touch briefly on the basics of probability (with specific reference to Bayes theorem) and delve into the details of mean and variance of random variables. This topic very neatly ties together a concept that we have covered (the mean) with one we are yet to cover (variance).

4Distributing Data

Lesson 4 is all about distributing data. You will learn about the various data distributions (with reference to the central limit theorem) and understand how to use mean, median and standard deviation to know how your data is distributed. Lastly, we will also expand on skewness and kurtosis, so tune in if you are dying to know what this means for your data.

5How Confident Are You In The Sample?

Being confident in your sample is important. This lesson will focus on understanding the difference between a sample and a population as well as when to use variance or standard deviation for each. We will also cover confidence intervals in more detail, and by the end of this lesson you will be well on your way to feeling more confident!

6Hypothesizing About The Outcome

Understanding what a hypothesis is an important step in your journey. We will expand on what a null and alternative hypothesis is and explore the difference between a Type 1 and Type 2 error. This lesson will also include more information on the central limit theorem/ the law of large numbers to enlighten us on this topic.

7Testing For Differences: Categorical Vars

Our penultimate lesson is focused on testing for differences (categorical vars). We will explore one sample tests, the difference between 2 means of 2 populations as well as Chi-square tests.

8Testing For Differences: Numerical Vars

Finally, we wrap up with understanding testing for differences (numerical vars). In this lesson one sample tests, the difference between 2 means of 2 populations and T-tests will be covered and by the end of this lesson you will have a firm and complete understanding of the basics of data and data analysis. The journey does not stop here and in Module 2 you can expect more complex concepts and a deeper understanding of the topic.

This course is fantastic! I learned so much so far, all topics are well explained.

The team do a great job at cramming so much information into each hourly session. It never feels like cramming though and stays in the memory easily.
