Using a line chart instead of a scatter chart might not make sense. We also use charts and graphs to check the performance of models or while categorizing or clustering the data.Ĭhoosing a correct chart to communicate your findings about data is also important. Many visuals are used in the data exploration phase to find outliers, correlation between features, etc. We need visualization as a visual summary of the data, because it’s easier to understand for identifying relations and patterns. Data visualization can be done in two forms – tabular and graphical. Data visualization is nothing but a mapping between tables or graphs and data (inputs or outputs). We can use visuals to represent the data at any point in our project. checking data distribution, finding correlation, finding outliers and missing values, etc.ĭata Visualizations aren’t part of any specific phase in a data analytics project. It’s not a single step phase, but we get to determine a lot about our data during data exploration e.g. Whatever you decide to do in the later phases (creating/selecting a machine learning model or summarizing your findings), will depend on the assumptions you make in the exploration phase. Go to Access 2013 TutorialĬheck out what Access used to look like back in 2003! See how far Access has come since the early days.When you are working on a data science project or trying to find data insights to strategize your plans, there are two key steps that can not be avoided – Data Exploration and Data Visualization.ĭata Exploration is an integral part of EDA ( Exploratory Data Analysis). There's not much difference in functionality between Access 20, so you could do both tutorials with either 2013 or 2016. Microsoft Access 2013 is the predecessor to Access 2016. Here are tutorials from previous versions of Access. This tutorial covers the basic concepts of databases, and the examples use Microsoft Access, so that will make it easier for you once you return here. If you don't currently have an understanding of how databases work, no worries - I have written a basic database tutorial just for you! Includes mini-tutorials for doing things like, creating a totals row, creating a parameter query, password protecting your database, doing a mail merge, and much more. Large list of "how to" articles that show step-by-step instructions for doing common tasks in Access. It assumes a basic understanding of databases and how they work.
This Microsoft Access tutorial is aimed at anyone who wishes to learn how to use Microsoft Access.
