1. What is the difference between the RANK() and DENSE_RANK() functions?
The RANK() function in the result set defines the rank of each row within your ordered partition. If both rows have the same rank, the next number in the ranking will be the previous rank plus a number of duplicates. If we have three records at rank 4, for example, the next level indicated is 7. The DENSE_RANK() function assigns a distinct rank to each row within a partition based on the provided column value, with no gaps. If we have three records at rank 4, for example, the next level indicated is 5.
2. Explain One-hot encoding and Label Encoding. How do they affect the dimensionality of the given dataset?
One-hot encoding is the representation of categorical variables as binary vectors. Label Encoding is converting labels/words into numeric form. Using one-hot encoding increases the dimensionality of the data set. Label encoding doesn’t affect the dimensionality of the data set. One-hot encoding creates a new variable for each level in the variable whereas, in Label encoding, the levels of a variable get encoded as 1 and 0.
3. What is the shortcut to add a filter to a table in EXCEL?
The filter mechanism is used when you want to display only specific data from the entire dataset. By doing so, there is no change being made to the data. The shortcut to add a filter to a table is Ctrl+Shift+L.
4. What is DAX in Power BI?
DAX stands for Data Analysis Expressions. It's a collection of functions, operators, and constants used in formulas to calculate and return values. In other words, it helps you create new info from data you already have.
5. Define shelves and sets in Tableau?
Shelves: Every worksheet in Tableau will have shelves such as columns, rows, marks, filters, pages, and more. By placing filters on shelves we can build our own visualization structure. We can control the marks by including or excluding data.
Sets: The sets are used to compute a condition on which the dataset will be prepared. Data will be grouped together based on a condition. Fields which is responsible for grouping are known assets. For example – students having grades of more than 70%.

📊 Data Analytics: A-Z! 🚀
Data Analytics is the art and science of examining raw data to draw conclusions about that information. It's a powerful field that helps businesses and organizations make informed decisions, improve efficiency, and gain a competitive edge.
Here's a journey through Data Analytics, from the basics to advanced topics:
A - Applications:
• Across industries: Finance, Healthcare, Marketing, Retail, Supply Chain, etc.
• Use cases: Customer segmentation, fraud detection, risk management, predictive maintenance, market research, and more.
B - Business Intelligence (BI):
• Tools and technologies for analyzing business data and presenting it in an easily understandable format (dashboards, reports).
• Examples: Power BI, Tableau, Qlik Sense.
C - Cleaning Data:
• The process of identifying and correcting errors, inconsistencies, and inaccuracies in a dataset.
• Techniques: Handling missing values, removing duplicates, correcting typos, standardizing formats.
D - Data Visualization:
• Graphical representation of data using charts, graphs, maps, and other visual elements.
• Goal: Communicate insights effectively and make data easier to understand.
E - ETL (Extract, Transform, Load):
• The process of extracting data from various sources, transforming it into a consistent format, and loading it into a data warehouse or other storage system.
F - Formulas (Excel):
• Essential for performing calculations and data manipulation in Excel.
• Examples: SUM, AVERAGE, IF, VLOOKUP, COUNTIF.
G - Google Analytics:
• A web analytics service that tracks and reports website traffic.
• Used to analyze user behavior, measure the effectiveness of marketing campaigns, and improve website performance.
H - Hypothesis Testing:
• A statistical method used to determine whether there is enough evidence to support a hypothesis about a population.
• Common tests: T-tests, Chi-square tests, ANOVA.
I - Insights:
• Actionable conclusions and discoveries derived from data analysis.
• Insights should be clear, concise, and relevant to the business context.
J - JOINs (SQL):
• A SQL clause used to combine rows from two or more tables based on a related column.
• Types: INNER JOIN, LEFT JOIN, RIGHT JOIN, FULL OUTER JOIN.
K - Key Performance Indicators (KPIs):
• Measurable values that demonstrate how effectively a company is achieving key business objectives.
• Examples: Revenue growth, customer satisfaction, market share.
L - Libraries (Python):
• Essential Python libraries for data analysis:
• Pandas: Data manipulation and analysis.
• NumPy: Numerical computing.
• Matplotlib & Seaborn: Data visualization.
• Scikit-learn: Machine learning.
M - Machine Learning (ML):
• A type of artificial intelligence that enables computers to learn from data without being explicitly programmed.
• Used for tasks like prediction, classification, and clustering.
N - Normalization:
• A data preprocessing technique used to scale numerical data to a common range, improving the performance of machine learning algorithms.
O - Outliers:
• Data points that are significantly different from other values in a dataset.
• Can be caused by errors, anomalies, or natural variations.
P - Pivot Tables (Excel):
• A powerful tool in Excel for summarizing and analyzing large datasets.
• Allows you to quickly group, filter, and aggregate data.
Q - Queries (SQL):
• Requests for data from a database.
• Used to retrieve, insert, update, and delete data.
R - Regression Analysis:
• A statistical method used to model the relationship between a dependent variable and one or more independent variables.

V - Visualizations:
• Charts, graphs, maps, and other visual elements used to represent data.
• Choose the right visualization to effectively communicate your insights.
W - WHERE Clause (SQL):
• A SQL clause used to filter rows based on specified conditions.
• Essential for retrieving specific data from a table.
X - Exploratory Data Analysis (EDA):
• An approach to analyzing data to summarize its main characteristics, often with visual methods.
• Goal: To gain a better understanding of the data before performing more formal analysis.
Y - Y-axis (Charts):
• The vertical axis in a chart, typically used to represent the dependent variable or the value being measured.
Z - Zero-Based Thinking:
