Questions and Answers

What should a researcher have a sufficient handle on at the point of data collection?

the research questions and approach they will be undertaking

What is the risk of gathering data without sufficient clarity?

gathering data that does not end up being relevant to the line of inquiry

When is an iterative approach possible?

when the data collection process is under the researcher's control and is not too arduous

What can the task of collecting sufficient data or knowing when to stop dwarf?

What is sampling bias and how can it be introduced during data collection?

Sampling bias is when the means of selecting participants or data points in a study introduces a bias in the results. An example of sampling bias is dividing computer systems into server and workstation groups without accounting for the fact that there are typically more workstations than servers in an enterprise.

What is systemic bias and how does it impact the research lifecycle?

Systemic bias is a form of bias that underlies the entire research lifecycle. It refers to biases that are present throughout the entire research process. An example of systemic bias is when a drug company funds studies on their own drugs to determine safety and effectiveness, introducing bias in the research findings. Signup and view all the answers

Give an example of systemic bias in the field of cybersecurity research.

An example of systemic bias in cybersecurity research is when an antivirus/antimalware or IDS vendor contracts a university or research institution to conduct a security/vulnerability or performance assessment. This practice can introduce bias in the research findings. Signup and view all the answers

What are some reasons for sampling data instead of using the entire dataset?

Some reasons for sampling data instead of using the entire dataset include cost-prohibitive or restricted access to the entire dataset. Sampling allows researchers to obtain a representative subset of the data without incurring excessive costs or breaching data access restrictions. Signup and view all the answers

Explain the potential bias introduced when dividing computer systems into server and workstation groups without considering their relative proportions in an enterprise.

The potential bias introduced when dividing computer systems into server and workstation groups without considering their relative proportions in an enterprise is that it fails to account for the fact that there are typically more workstations than servers. This can skew the results and lead to incorrect conclusions about the overall population of computer systems in the enterprise. Signup and view all the answers

Study Notes

Data Collection Fundamentals

A researcher should have a sufficient understanding of the research question, objectives, and variables at the point of data collection.
Insufficient clarity during data collection can lead to unclear or incomplete data, wasting resources and potentially producing misleading results.

Iterative Approach

An iterative approach is possible when data collection and analysis are repeated in cycles, refining the research question and methods until sufficient data is collected.

Data Collection Challenges

The task of collecting sufficient data or knowing when to stop can be dwarfed by the complexity of the research question, data quality issues, or limited resources.

Pitfalls in Data Collection

Several pitfalls in data collection can be alleviated by having a clear research question, using multiple sources, and regularly reflecting on the data collection process.

Sampling Bias

Sampling bias occurs when the sample is not representative of the population, leading to inaccurate conclusions.
Sampling bias can be introduced during data collection through methods such as convenience sampling, non-response bias, or measurement bias.

Systemic Bias

Systemic bias refers to the flaws in the research lifecycle that can produce misleading results, including data collection, analysis, and interpretation.
Systemic bias can impact the research lifecycle by producing biased results, perpetuating stereotypes, and misleading policy decisions.

Example of Systemic Bias in Cybersecurity Research

In cybersecurity research, systemic bias can occur when researchers primarily focus on high-profile attacks, ignoring less prominent threats, and creating a biased understanding of the threat landscape.

Sampling Data

Sampling data instead of using the entire dataset can be necessary due to constraints such as time, resources, or data quality issues.
Reasons for sampling data include reducing data volume, improving data quality, and increasing the speed of analysis.

Bias in Computer System Classification

Dividing computer systems into server and workstation groups without considering their relative proportions in an enterprise can introduce bias, as it may not accurately represent the distribution of systems in the organization.
This bias can lead to inaccurate conclusions about the security posture of the organization.
