Being a data analyst requires a variety of skills in Excel.

If you dream of working as an analyst, but you lack a few skills in order to master MS-Excel, TEST4U Data Analyst is the ultimate know-how interactive tutor!

We have equipped TEST4U with the following, in order to help you acquire these valuable skills:

  • We will help you learn the usage of more than 180 Excel functions, about:

    • Text manipulation
    • Mathematical calculation
    • Logical decisions
    • All the lookup functions you can use to retrieve data from your sheets
    • Almost all the financial functions and
    • Almost all the statistical functions Excel has to offer
  • You will learn about array and multi-sheet formulas, which will give you the needed flexibility to use data from multiple sources.

  • The built-in what-if tools of Excel along with the Solver add-in are the sure way to answer everyday questions and problems you will face (for example how much should a factory increase production, to meet their quota for next month).

  • No one can avoid mistakes, but the chapter about Auditing tools will teach how to minimize them

  • Data Management: The chapter in data management will expand your knowledge on data manipulation showing you ways to:

    • Import data from various sources
    • Filter data
    • Sort data
    • Use form controls in order to be able to create dashboard-like sheets
    • Use the Data Analysis Tool Pak add-in.
  • The data analysis Tool Pak add-in along with the Solver add-in are the main tools you can use to answer to more specialized questions, which are part of the daily routine for someone who is doing statistical analysis, or business modelling. You will learn how to answer these questions with over thirty examples inspired by real life (display and interpret Regression statistics, predict a company’s revenues or execute a Monte Carlo simulation).

  • You will be able to derive useful information from the data in a Pivot Table: Once you finish your training, you will be able to use pivot Tables at their full extent, including the use of slicers, trendlines, and pivot charts. In addition, you will learn how to use all your data with Power View.

  • Using large amount of data can prove to be a lot difficult, especially if you want to extract a fragment of them. Excel provides a tool to create database like queries on your Excel data. For this tool, that was called Power Query on previous Excel versions, we decided to devote a complete chapter.

  • Power Maps! One of the most impressive add-ins of Excel, for which we have dedicated a whole chapter!

  • Large amounts of data from various sources are no longer a headache! These chapters will change the way you deal with them:

    • Power Pivot add-in
    • Cube
    • DAX functions
  • Sharing: All professional work you do must be shared with your boss or colleagues. We will teach you how to save your workbooks in a variety of different formats and how to share your worksheets with your team.

  • There is an extensive chapter on basic Excel training, in case you want to refresh on your Excel knowledge, or if you are newcomer to it
