What Is Data Science? A Beginner’s Guide To Data Science

L hope you enjoyed reading my blog and understood what Data Science is. I urge you to see this Data Science video tutorial that explains what is Data Science and all that we have discussed in the blog. Go ahead, enjoy the video and tell me what you think. Once we have executed the project successfully, we will share the output for full deployment. First, we will load the data into the analytical sandbox and apply various statistical functions on it. For example, R has functions like describe which gives us the number of missing values and unique values.

In this phase, we will run a small pilot project to check if our results are appropriate. We will also look for performance constraints if any. If the results are inaccurate, we need to replan and rebuild the model.

We can also use the summary function which will give us statistical information like mean, median, range, min and max values. Finally, we get the clean data as shown below which can be used for analysis. So, we will clean and preprocess this data by removing the outliers, filling up the null values and normalizing the data type. If you remember, this is our second phase which is data preprocessing. This data has a lot of inconsistencies like missing values, blank columns, abrupt values and incorrect data format which need to be cleaned.
