Find Interview Questions for Bis research

Right Answer:
Buyer personas are semi-fictional representations of a company's ideal customers, based on market research and real data about existing customers. They are created by gathering information through surveys, interviews, and analyzing customer demographics, behaviors, and motivations to identify common traits and needs.

Right Answer:
Data analysis in market research is the process of systematically examining and interpreting data collected from surveys, focus groups, or other sources to identify trends, patterns, and insights that inform business decisions and strategies.

Right Answer:
Market research is the process of gathering, analyzing, and interpreting information about a market, including information about the target audience, competitors, and industry trends. It is important because it helps businesses understand customer needs, identify market opportunities, make informed decisions, and reduce risks associated with launching new products or services.

Right Answer:
A questionnaire is a set of written questions used to gather information from respondents. To design one effectively, follow these steps:

1. Define the objective: Clearly outline what information you want to gather.
2. Identify the target audience: Know who will be answering the questions.
3. Choose the question type: Use a mix of open-ended and closed-ended questions.
4. Keep it concise: Limit the number of questions to avoid respondent fatigue.
5. Use clear and simple language: Ensure questions are easy to understand.
6. Pilot test: Test the questionnaire with a small group to identify any issues.
7. Revise based on feedback: Make necessary adjustments before the final distribution.

Right Answer:
Clustering in data analysis is the process of grouping similar data points together based on their characteristics, without prior labels. It is an unsupervised learning technique. In contrast, classification involves assigning predefined labels to data points based on their features, using a supervised learning approach.

Right Answer:
SQL (Structured Query Language) is used in data analysis to query, manipulate, and manage data stored in relational databases. It allows analysts to retrieve specific data, perform calculations, filter results, and aggregate information to derive insights from large datasets.

Right Answer:
Supervised learning uses labeled data to train models, meaning the output is known, while unsupervised learning uses unlabeled data, where the model tries to find patterns or groupings without predefined outcomes.

Right Answer:
Exploratory Data Analysis (EDA) is the process of analyzing and summarizing datasets to understand their main characteristics, often using visual methods. It helps identify patterns, trends, and anomalies in the data before applying formal modeling techniques.

Right Answer:
**CFD (Context Flow Diagram)**: A high-level diagram that shows the flow of information between external entities and the system, helping to define system boundaries and interactions.

**DFD (Data Flow Diagram)**: A visual representation that illustrates how data moves through a system, detailing processes, data stores, and data flows, typically used to analyze and design systems.

**Functional Documentation**: A comprehensive document that outlines the functionalities of a system, including requirements, use cases, and specifications, serving as a guide for development and testing.

Working capital is the difference between a company's current assets and current liabilities, indicating the short-term financial health and operational efficiency of the business.

Right Answer:
Content analysis is a research method used to systematically analyze communication content, such as texts, speeches, or media, to identify patterns, themes, and meanings.

Right Answer:

Analyzing survey or questionnaire data means turning raw responses into meaningful insights. The goal is to understand what your audience thinks, feels, or experiences based on their answers.

There are two main types of survey data:

- Quantitative data: Numerical responses (e.g., ratings, multiple-choice answers)
- Qualitative data: Open-ended, written responses (e.g., comments, opinions)

—

🔍 How to Analyze Survey Data:

1. Clean the Data
 Remove incomplete or inconsistent responses. Make sure all data is accurate and usable.

2. Categorize the Questions
 Separate your questions into types:
– Yes/No or Multiple Choice (Closed-ended)
 - Rating Scales (e.g., 1 to 5)
 - Open-Ended (Written answers)

3. Use Descriptive Statistics
 For closed-ended questions:
– Count how many people chose each option
 - Calculate percentages, averages, and medians
 - Use charts like bar graphs or pie charts to visualize trends

4. Look for Patterns and Trends
 Compare responses between different groups (e.g., by age, location, or gender)
 Identify common opinions or issues that many people mentioned

5. Analyze Open-Ended Responses
 Group similar comments into categories or themes
 Highlight key quotes that illustrate major concerns or ideas

6. Draw Conclusions
 What do the results tell you?
 What actions can be taken based on the responses?
 Are there surprises or areas for improvement?

Right Answer:

Percentages and ratios are simple but powerful tools for understanding and comparing data. They help you express relationships between numbers in a way that’s easy to read, compare, and communicate.

Both are commonly used in business reports, surveys, research, and everyday decision-making.

—

🔢 How to Calculate Percentages:

A percentage shows how much one value is out of 100.

👉 Formula:
Percentage = (Part ÷ Total) × 100

📊 Example:
If 40 out of 200 customers gave a 5-star review:
(40 ÷ 200) × 100 = 20%
So, 20% of customers gave top ratings.

✅ Interpreting It:
You can now say, “20% of our customers were highly satisfied.”

—

📏 How to Calculate Ratios:

A ratio compares two quantities directly, showing how many times one value contains or relates to another.

👉 Formula:
Ratio = Value A : Value B

Right Answer:

Correlation is a statistical measure that shows the relationship between two variables. In simple terms, it tells you whether — and how strongly — two things are connected.

For example, if ice cream sales increase whenever the temperature goes up, we say there is a positive correlation between temperature and ice cream sales.

Right Answer:

Interpreting and comparing data across different time periods or categories helps you spot patterns, measure progress, and make informed decisions. It allows you to see what has changed, what stayed the same, and what might need attention.

Whether you’re comparing sales by month, customer feedback by product, or website traffic by country — the goal is to understand how performance or behavior differs over time or between groups.

—

🔍 How to Interpret Data Over Time:

1. Look for Trends
 Is the data increasing, decreasing, or staying flat over time?
 Example: Are your monthly sales growing quarter by quarter?

2. Compare Periods
 Compare the same data from different time frames:
 This year vs. last year, or before vs. after a marketing campaign.

3. Use Averages and Percent Changes
 Instead of just raw numbers, calculate averages, growth rates, and percentage differences for better understanding.

4. Visualize with Charts
 Use line charts, bar graphs, or area charts to clearly show how things have changed over time.

—

🔍 How to Compare Data by Categories:

1. Group the Data
 Organize your data by categories such as location, department, product, or customer type.

2. Use Side-by-Side Comparisons
 Bar charts, grouped tables, or dashboards make it easier to compare categories at a glance.

3. Look for Outliers or Top Performers
 Which category performed the best? Which underperformed?

4. Ask “Why?”
 After identifying the differences, try to understand the reason behind them.

Right Answer:

Interpreting data from histograms and frequency distributions means understanding how values in a dataset are spread across different ranges. These tools help you see patterns, identify where most values lie, and spot any unusual data.

A frequency distribution is a table that shows how often each value (or range of values) occurs. A histogram is a visual version of this—a bar chart where each bar represents a range of values and its height shows how many times those values appear.
