Practical Research 2 Quiz

What are the different types of data collection methods used in practical research?

• Guessing the results

• The different types of data collection methods used in practical research include surveys, interviews, observations, experiments, and secondary data analysis.

• Sending emails to friends

• Asking random people on the street

What are the advantages and disadvantages of using surveys as a data collection method?

• Advantages: Surveys can gather a large amount of data from a diverse group of people. They are relatively easy and cost-effective to administer. Disadvantages: Surveys may suffer from response bias and may not always provide in-depth or accurate information.

• Disadvantages: Surveys always provide accurate and in-depth information.

• Advantages: Surveys are time-consuming and expensive to administer.

• Advantages: Surveys can only gather data from a small and homogenous group of people.

What is the role of hypothesis testing in statistical analysis techniques?

• Hypothesis testing is used to create random samples for analysis

• Hypothesis testing is used to prove a hypothesis with absolute certainty

• Hypothesis testing is used to determine the mean of a population parameter

• Hypothesis testing is used to make inferences about a population parameter based on sample data, and to determine if there is enough evidence to support a claim or hypothesis.

Discuss the importance of sample size in practical research.

• The generalizability of study findings is not affected by sample size

• A smaller sample size always provides more accurate results

• The importance of sample size in practical research is that it affects the reliability and generalizability of the study findings. A larger sample size generally provides more accurate results and allows for better representation of the population being studied.

• Sample size has no impact on the reliability of research findings

What are the common statistical analysis techniques used to analyze experimental data?

• Counting techniques

• Some common statistical analysis techniques used to analyze experimental data include t-tests, ANOVA, regression analysis, chi-square tests, and correlation analysis.

• Descriptive statistics

• Qualitative analysis

How does the choice of experimental design impact the validity of research findings?

• The choice of experimental design has no impact on the validity of research findings

• The choice of experimental design can impact the validity of research findings by influencing the control of variables, the ability to make causal inferences, and the generalizability of the results.

• Validity of research findings is solely determined by the sample size, not the experimental design

• Experimental design only impacts the speed of data collection, not the validity of research findings

What are the different types of sampling methods used in practical research?

• Random sampling

• Convenience sampling

• Purposive sampling

• Snowball sampling

What are the advantages and disadvantages of using interviews as a data collection method?

• Advantages: Interviews allow for in-depth exploration of responses. Disadvantages: Interviews can be time-consuming and may suffer from interviewer bias.

• Advantages: Interviews are quick and easy to conduct. Disadvantages: Interviews provide limited information.

• Advantages: Interviews always provide accurate information. Disadvantages: Interviews are expensive to administer.

• Advantages: Interviews can only gather data from a small and homogenous group of people. Disadvantages: Interviews are not suitable for qualitative research.

Discuss the importance of data analysis in practical research.

• Data analysis is not important in practical research.

• Data analysis is important for drawing meaningful conclusions from research findings and identifying patterns or trends in the data.

• Data analysis is only important for qualitative research, not quantitative research.

• Data analysis is important for data collection, not for drawing conclusions.
