Data Analysisis the technique of collecting, transforming, and organizing data to make future predictions and informed data-driven decisions. It also helps to find possible solutions for a business problem. There are six steps for Data Analysis. They are: 1. Ask or Specify Data Requirements 2. Prepare or Collect Data 3. Clean and Process 4. Analyze...
NumPyis an array processing package in Python and provides a high-performance multidimensional array object and tools for working with these arrays. It is the fundamental package for scientific computing with Python.
Python Pandas Is used for relational or labeled data and provides various data structures for manipulating such data and time series. This library is built on top of the NumPy library. This module is generally imported as: Here, pd is referred to as an alias to the Pandas. However, it is not necessary to import the library using the alias, it just ...
In order to concat the dataframe, we use concat()function which helps in concatenating the dataframe. This function does all the heavy lifting of performing concatenation operations along with an axis of Pandas objects while performing optional set logic (union or intersection) of the indexes (if any) on the other axes. Python Pandas Concatenate Da...
When we need to combine very large DataFrames, joins serve as a powerful way to perform these operations swiftly. Joins can only be done on two DataFrames at a time, denoted as left and right tables. The key is the common column that the two DataFrames will be joined on. It’s a good practice to use keys that have unique values throughout the column...
In order to join the dataframe, we use .join()function this function is used for combining the columns of two potentially differently indexed DataFrames into a single result DataFrame. Python Pandas Join Dataframe Output: For more information, refer to our Pandas Merging, Joining, and Concatenatingtutorial For a complete guide on Pandas refer to ou...
Matplotlib is easy to use and an amazing visualizing library in Python. It is built on NumPy arrays and designed to work with the broader SciPy stack and consists of several plots like line, bar, scatter, histogram, etc.
Exploratory Data Analysis (EDA)is a technique to analyze data using some visual Techniques. With this technique, we can get detailed information about the statistical summary of the data. We will also be able to deal with the duplicates values, outliers, and also see some trends or patterns present in the dataset. Note:We will be using Iris Dataset...

May 4, 2023 · Working with data. To be a data scientist means knowing a lot about several areas. But first and foremost, you have to get comfortable with data. What kinds of data are there, how can it be stored, and how can it be retrieved? Is it real-time data or historical data? Can it be queried with SQL?
Sep 30, 2024 · Exploratory Data Analysis in Python. Exploratory data analysis (EDA) is a critical initial step in the data science workflow. It involves using Python libraries to inspect, summarize, and visualize data to uncover trends, patterns, and relationships. Here’s a breakdown of the key steps in performing EDA with Python: 1. Importing Libraries:
