What is Data Science?

Data science is the science that studies data. Using data science in our life change our perspective and overview of things around us.

Regarding wikipedia data science defined as :

Data science is a multi-disciplinary field that uses scientific methods, processes, algorithms and systems to extract knowledge and insights from structured and unstructured data
In general data science is extracting meaning and insights from data then predicting new coming data.

In simple terms, a data scientist’s job is to analyze data for actionable insights.

specific tasks data scientists do:

• Collecting and Loading the data that we will explore.
• Determining if the data set needs cleansing
• Cleaning data and preparing it for analysis
• Perform Exploratory Data Analysis on the data to understand the nature of our data set
• Visualizing data and try to understand the nature of the data visually.
• Determine the right machine learning algorithm to perform on the data set.
• Create our machine learning model
• divide our data set into training data to train our model with it and testing data to test our model with.
• Fit the training data into the model.
• Test the model with the testing data set we have.
• Calculate the accuracy score of the model to evaluate the model we built.

For each task I'll try to explain it with examples and in very simple way in the next articles...
