What Exactly is Athena, and How does it Function?Amazon Athena is an Amazon Web Services (AWS) query service that allows you to evaluate data stored in Amazon S3 using regular SQL queries. Athena is a serverless service. Thus there are no servers to operate, and you simply pay for the queries you perform. To use Amazon Athena, create tables in Athena that refer to data in Amazon S3. You can construct tables in Athena that point directly to your S3 data or utilize the Amazon Glue Data Catalog to define external tables that indicate your S3 data. When you’ve defined your tables, you can use the Athena Query Editor or any other standard SQL client to perform SQL queries against them.
When you perform a query in Amazon Athena, the service scales up the resources required to conduct the query and provides the results to you. Athena utilizes Presto, an open-source distributed SQL query engine, to perform your requests. Presto breaks down your query into small jobs spread across a cluster of Amazon EC2 servers. Each instance executes a subset of the query, and the results are merged to get the final output. CSV, JSON, ORC, and Parquet are among the data formats supported by Amazon Athena. You can also use Athena to analyze structured data in relational databases by crawling your database using Amazon Glue and creating a table definition that refers to your data.
Overall, Amazon Athena provides a simple and powerful approach to analyzing data in S3 without sophisticated data infrastructure setup and management. Users may evaluate data stored in various formats using standard SQL queries, and the serverless aspect of the service makes it simple to expand and improve query performance.

1. Name and explain a few methods/techniques used in Statistics for analyzing the data?Answer:
It is an important technique in statistics. The number of the quantity obtained by summing two or more numbers/variables and then dividing the sum by the number of numbers/variables.
If the group is odd, arrange the numbers in the group from smallest to largest. The median will be the one that is exactly sitting in the middle, with an equal number on either side of it. If the group is even, arrange the numbers to pick the two middle numbers and add them, then divide by 2. It will be the median number of that set.
The mode is also one of the types for finding the average. A mode is a number that occurs most frequently in a group of numbers. Some series might not have any mode; some might have two modes which is called bimodal series.
In the statistics study, the three most common ‘averages’ in statistics are Mean, Median, and Mode.
Standard Deviation measures how much your data is spread out in statistics.
Regression is an analysis in statistical modeling. It’s a statistical process for measuring the relationships among the variables; it determines the strength of the relationship between one variable and a series of other changing independent variables.
2. Explain statistics branches?The two main branches of statistics are descriptive statistics and inferential statistics.
Descriptive Statistics methods include displaying, organizing, and describing the data.

5. What is linear regression in statistics?Linear regression is one of the statistical techniques used in the predictive analysis; this technique will identify the strength of the impact that the independent variables show on deepened variables.
6. List the Sampling Methods?In a Statistical study, a Sample is nothing but a set of or a portion of collected or processed data from a statistical population by a structured and defined procedure. The elements within the sample are known as sample points.
Below are the 4 sampling methods:
Cluster Sampling: IN the cluster sampling method, the population will be divided into groups or clusters.
Simple Random: This sampling method simply follows pure random division.
Stratified: In stratified sampling, the data will be divided into groups or strata.
Systematical: Systematical sampling method picks every kth member of the population.
7. What is the P-value, and explain it? 8. What is Data Science, and what is the relationship between Data science and Statistics?Data Science is simply data-driven science; it involves the interdisciplinary field of automated scientific methods, algorithms, systems, and processes to extract insights and knowledge from data in any form, either structured or unstructured. Data Science and Data mining have similarities, both useful abstract information from data.
Data Sciences include Mathematical Statistics along with Computer science and Applications. By combing aspects of statistics, visualization, applied mathematics, and computer science Data Science is turning the vast amount of data into insights and knowledge.
Statistics is one of the main components of Data Science. Statistics is a branch of mathematics commerce with the collection, analysis, interpretation, organization, and data presentation.
9. What is correlation and covariance in statistics?Covariance and Correlation are two mathematical concepts; these two approaches are widely used in statistics. Correlation and Covariance establish the relationship and measure the dependency between two random variables. Though the work is similar between these two in mathematical terms, they are different from each other.
Correlation: Correlation measures how strongly two variables are related.
Covariance: In covariance, two items vary together, and it’s a measure that indicates the extent to which two random variables change in a cycle. It is a statistical term; it explains the systematic relation between a pair of random variables, wherein changes in one variable are reciprocal by a corresponding change in another variable.

Here, we have prepared the important GIT Interview Questions and Answers which will help you get success in your interview. These questions will help students build their concepts around GIT and help them ace the interview.
Part 1 – GIT Interview Questions (Basic)This first part covers basic Interview Questions and Answers.
Q1. Define GIT and repository in GIT?GIT is a version control system or distributed VCS to use for different projects and programmers to centralize the code of a particular project at one place. The repository in GIT consists of a directory named .git, in which it keeps all the data for the repository. The content remains private to git. GIT is recommended to use as it can be used for any project without any restrictions.
Q2. Difference between GIT and SVN?GIT is referred to as distributed control version system and SVN is referred as a centralized version system. While working with GIT, the code can be taken once in your local machine and changes can be done and committed, and an end, the whole can be committed in one go to master branch. It means it does not require connection with a network for check in the code all the time. While working with SVN, it needs to be connected with the network when any code needs to be committed.
Q3. Mention GIT commands that are mainly used?There are some commands that are mostly used:
GIT status: To know the comparison between the working directories and index.
GIT diff: to know the changes between the commits and the working tree.
GIT stash applies: to get the saved changes on the working directory.
GIT log: to know specific commit from the history of commits.
GIT add: It adds file changes in an existing directory to index.
GIT rm: It removes a file from the staging area.
GIT init: creating a new repository.
GIT clone: to copy or check out the working repository.
GIT commit: committing the changes.
GIT PUSH: sending the changes to the master branch.
GIT pull: fetch the code already in the repository.
GIT merge: merge the changes on the remote server to the working directory.
Git reset: to reset or drop all the changes and commits.
Q4. Explain the purpose of branching and its types? Q5. How do you resolve ‘conflict’ in GIT?When one developer takes the code from GIT in the local system and does the change and tries to commit that code but already another developer has committed the changes. At that point, conflict arises while committing the change. To resolve the conflict in GIT, files need to be edited to fix the conflicting changes and then add the resolved files by running the GIT add command and commit the repaired merge. GIT identifies the position and sets the parents to commit correctly.
Part 2 – GIT Interview Questions (Advanced) Q6. Explain Git stash and Git stash drop?Git Stash takes the current state of working directory and index. It pushes into the stack for later and returns cleaning the working directory. It helps in instances the work in the project and switches the branches to work. Git stash drop is used when you are done and want to eliminate the stashed item from the list, then running the GIT stash drop command will remove last added stash item by default and can also remove the specific item if any argument is included or mentioned.
Q7. What is GIT bisect and its purpose? Q9. Explain head in git?This is the frequently asked GIT Interview Questions in an interview. A head in GIT is referred as commit object. Master is referred to as the default head in every repository. The repository can contain any number of head.
Q10. Explain SubGit and its use?SubGit is a tool for smooth, stress-free SVN to GIT migration. It is a solution for company-wide migration from SVN to GIT. It is better than git-svn, no requirement to change the infrastructure that is already placed allows using all git and svn features, and provides genuine free migration experience.
Q11. How to rebase master in GIT?Rebasing is defined as the process of moving a branch to a new base commit. The rule of git rebase is to never use it on public branches. To synchronize two branches is to merge them together, which results in extra merge commit and two sets of commits will contain the same changes.
