Data Analysis is the sexiest job of the 21st century by Harvard Business Review. Data analysis has a big demand in the job market. You just need to have skills for a job and a graduation degree. The role of a data analyst is to collect processes and get insights through mathematical tools from the data. You must analyze your interest in this field by assessing your inclination towards numbers, and algebraic functions. Based on your assessment you can choose this career path. The skills that you need to develop for guaranteed jobs are as given below.
- Microsoft Excel: The data is of no use until properly structured. Excel has the functionality to make data management more convenient.
- Basic SQL skills are quintessential for fetching data from the database, updating and deleting existing data and adding new data to the database.
- Basic web development skills- R and Python are the most popular programming language to learn. R supports statistical computing and graphics. Python will help you handle larger data.
- Ability to find patterns in large data sets.
- Data mapping skills.
R Programming
You should have a good grasp of some of the concepts of R language. Dplyr is a bridge between R and SQL.
ggplot2 is the grammar of graphics it will help you prepare network plots.
reshape2: It is for reshaping the data. It has a collection of functions that will help you to convert data between wide and long formats and vice versa. It is for tidying data. The various forms of data reshaping in data frames are
- Transpose of a Matrix
- Joining Rows and Columns
- Merging of Data Frames
- Melting and Casting
Python
The data analyst market is going to grow by 154 per cent this year and Python’s applicability to AI development is crucial. IEEE’s Spectrum 2019 survey has shown this language in the first spot. It has so many specialized libraries for all the purposes.
Machine Learning Algorithms
Machine learning algorithm takes the mathematical data and transforms it into the model. They are applied to solve regressive and classified problems. When machines are involved in classification, clustering, and anomaly detection then we must have to induct a machine learning model. Most Machine learning algorithm is classification-based where machine sort data into classes or regression-based where machine inputs the value based on the possibility.
The computational intelligence handling algorithm will help us to fetch insights from the structured data. So you must learn these algorithms. You need to stay ahead to be relevant in this field because there is cutthroat competition in this line of work.
