• Interviews, Observations, Content analysis, Longitudinal studies

• Surveys, Experiments, Case studies, Focus groups

• Surveys, Interviews, Observations, Experiments, Existing data analysis

• Questionnaires, Field trials, Meta-analysis, Correlational studies

Explain the difference between qualitative and quantitative data analysis techniques.

• Qualitative data analysis focuses on numbers, while quantitative data analysis focuses on words.

• Qualitative data analysis is objective, while quantitative data analysis is subjective.

• The main difference between qualitative and quantitative data analysis techniques is the type of data they focus on and the methods used to analyze that data.

• Qualitative data analysis uses statistical methods, while quantitative data analysis uses descriptive methods.

How do information retrieval systems help in accessing relevant data quickly?

• By randomly selecting data without any criteria

• By ignoring user queries and requests

• By using outdated software and hardware

• By utilizing indexing, querying, and ranking algorithms.

Discuss the various data storage solutions available for businesses.

• External hard drives

• Cloud storage, on-premises servers, network-attached storage (NAS), and storage area networks (SAN)

• CD-ROM storage

• Tape backups

What are the advantages of direct data collection methods?

• Direct data collection methods are time-consuming

• Direct data collection methods lack flexibility

• Indirect data collection methods are more cost-effective

• The advantages of direct data collection methods include accuracy, real-time data collection, customization, and control over data quality.

What are the disadvantages of indirect data collection methods?

• Indirect data collection methods are always more accurate

• Disadvantages of indirect data collection methods include time-consuming, less accurate, prone to bias, and lack depth in information gathered.

• Direct data collection methods are more time-consuming

• Bias is not a concern with indirect data collection methods

Describe a scenario where direct data collection would be more suitable than indirect methods.

• Indirect methods provide more detailed and reliable results.

• Direct data collection is more suitable when precise and specific information is needed.

• Direct data collection is prone to bias and inaccuracies.

• Indirect data collection is more efficient and cost-effective.

How can data analysis techniques help in making informed decisions?

• Data analysis techniques provide irrelevant information that confuses decision-making

• Data analysis techniques provide insights, trends, patterns, and relationships within the data to identify key factors, forecast trends, and evaluate strategies.

• Data analysis techniques are only useful for historical data and not future predictions

• Data analysis techniques slow down the decision-making process

Compare and contrast structured and unstructured data storage solutions.

• Structured data storage solutions are more flexible than unstructured data storage solutions

• Structured data storage solutions organize data in a predefined format with a schema, while unstructured data storage solutions store data without a predefined format.

• Unstructured data storage solutions require a predefined schema

• Structured data storage solutions store data in a random order

What are the potential risks associated with storing sensitive data in the cloud?

• Hardware upgrades, Physical theft, Inadequate encryption

• Data breaches, unauthorized access, lack of control over security measures, compliance issues, data loss
