Which of the following is a common method for conducting political surveys?

  1. Telephone surveys

  2. Online surveys

  3. In-person surveys

  4. All of the above


Correct Option: D
Explanation:

Political surveys can be conducted using a variety of methods, including telephone surveys, online surveys, and in-person surveys. The choice of method depends on factors such as the target population, the budget, and the time frame.

What is the difference between a sample and a population in the context of political surveys?

  1. A sample is a small group of people selected from the population.

  2. A population is the entire group of people that the survey is intended to represent.

  3. A sample is always representative of the population.

  4. A population is always larger than a sample.


Correct Option: A
Explanation:

In political surveys, a sample is a subset of the population that is selected to represent the entire population. The sample is used to collect data that can be generalized to the entire population.

What is the margin of error in a political survey?

  1. The maximum amount of error that is allowed in a survey.

  2. The range of values within which the true population parameter is likely to fall.

  3. The difference between the sample mean and the population mean.

  4. The number of people who participated in the survey.


Correct Option: B
Explanation:

The margin of error in a political survey is the range of values within which the true population parameter is likely to fall. It is calculated using a formula that takes into account the sample size and the level of confidence.

What is the purpose of weighting data in a political survey?

  1. To adjust for differences in the sample and the population.

  2. To make the sample more representative of the population.

  3. To reduce the margin of error.

  4. To increase the response rate.


Correct Option: A
Explanation:

Weighting data in a political survey is a statistical technique used to adjust for differences between the sample and the population. This is done by assigning different weights to different respondents in the sample, so that the sample is more representative of the population.

What is the difference between a cross-sectional survey and a longitudinal survey?

  1. A cross-sectional survey collects data from a sample of people at one point in time.

  2. A longitudinal survey collects data from the same sample of people over a period of time.

  3. Cross-sectional surveys are always more accurate than longitudinal surveys.

  4. Longitudinal surveys are always more expensive than cross-sectional surveys.


Correct Option: A
Explanation:

A cross-sectional survey collects data from a sample of people at one point in time. A longitudinal survey collects data from the same sample of people over a period of time. Cross-sectional surveys are typically less expensive and easier to conduct than longitudinal surveys.

What is the difference between a quantitative survey and a qualitative survey?

  1. Quantitative surveys collect numerical data.

  2. Qualitative surveys collect non-numerical data.

  3. Quantitative surveys are always more accurate than qualitative surveys.

  4. Qualitative surveys are always more expensive than quantitative surveys.


Correct Option: A
Explanation:

Quantitative surveys collect numerical data, such as percentages, means, and medians. Qualitative surveys collect non-numerical data, such as opinions, beliefs, and attitudes. Quantitative surveys are typically more structured than qualitative surveys.

What is the purpose of a focus group in political research?

  1. To gather in-depth information about public opinion on a particular issue.

  2. To test the effectiveness of a political campaign message.

  3. To generate ideas for new policies.

  4. To raise funds for political campaigns.


Correct Option: A
Explanation:

Focus groups are used in political research to gather in-depth information about public opinion on a particular issue. Focus groups typically consist of 8-12 people who are selected to represent the target population.

What is the difference between a poll and a survey?

  1. A poll is a type of survey that is conducted to measure public opinion.

  2. A survey is a type of poll that is conducted to collect data on a specific topic.

  3. Polls are always more accurate than surveys.

  4. Surveys are always more expensive than polls.


Correct Option: A
Explanation:

A poll is a type of survey that is conducted to measure public opinion. Polls are typically conducted on a large scale and are used to estimate the level of support for a particular candidate or policy. Surveys are a more general term that can be used to collect data on a variety of topics.

What is the difference between a random sample and a non-random sample?

  1. A random sample is a sample in which every member of the population has an equal chance of being selected.

  2. A non-random sample is a sample in which some members of the population have a higher chance of being selected than others.

  3. Random samples are always more accurate than non-random samples.

  4. Non-random samples are always less expensive than random samples.


Correct Option: A
Explanation:

A random sample is a sample in which every member of the population has an equal chance of being selected. Non-random samples are samples in which some members of the population have a higher chance of being selected than others. Random samples are typically more accurate than non-random samples.

What is the difference between a stratified sample and a cluster sample?

  1. A stratified sample is a sample in which the population is divided into strata, and then a sample is selected from each stratum.

  2. A cluster sample is a sample in which the population is divided into clusters, and then a sample of clusters is selected.

  3. Stratified samples are always more accurate than cluster samples.

  4. Cluster samples are always less expensive than stratified samples.


Correct Option: A
Explanation:

A stratified sample is a sample in which the population is divided into strata, and then a sample is selected from each stratum. A cluster sample is a sample in which the population is divided into clusters, and then a sample of clusters is selected. Stratified samples are typically more accurate than cluster samples.

What is the difference between a probability sample and a non-probability sample?

  1. A probability sample is a sample in which every member of the population has a known chance of being selected.

  2. A non-probability sample is a sample in which some members of the population have a higher chance of being selected than others.

  3. Probability samples are always more accurate than non-probability samples.

  4. Non-probability samples are always less expensive than probability samples.


Correct Option: A
Explanation:

A probability sample is a sample in which every member of the population has a known chance of being selected. Non-probability samples are samples in which some members of the population have a higher chance of being selected than others. Probability samples are typically more accurate than non-probability samples.

What is the difference between a census and a survey?

  1. A census is a complete count of the population.

  2. A survey is a sample of the population.

  3. Censuses are always more accurate than surveys.

  4. Surveys are always less expensive than censuses.


Correct Option: A
Explanation:

A census is a complete count of the population. A survey is a sample of the population. Censuses are typically more accurate than surveys, but they are also more expensive and time-consuming to conduct.

What is the difference between a dependent variable and an independent variable?

  1. A dependent variable is a variable that is affected by another variable.

  2. An independent variable is a variable that affects another variable.

  3. Dependent variables are always quantitative.

  4. Independent variables are always qualitative.


Correct Option: A
Explanation:

A dependent variable is a variable that is affected by another variable. An independent variable is a variable that affects another variable. Dependent variables are not always quantitative, and independent variables are not always qualitative.

What is the difference between a correlation and a causation?

  1. A correlation is a relationship between two variables.

  2. A causation is a relationship in which one variable causes another variable.

  3. Correlations are always positive.

  4. Causations are always negative.


Correct Option: A
Explanation:

A correlation is a relationship between two variables. A causation is a relationship in which one variable causes another variable. Correlations are not always positive, and causations are not always negative.
