Data Collection Methods Questions Quiz

Explanation
Secondary data refers to information that has already been collected and exists in some form. It is not collected first-hand, but rather obtained from sources such as research studies, surveys, government databases, or other existing data sets. This data can be used for various purposes, such as conducting further analysis, verifying findings, or comparing with primary data. It is considered secondary because it is not directly collected by the researcher or organization using it, but rather sourced from pre-existing data sources.

Explanation
Secondary data refers to data that has already been collected and analyzed by someone else for a different purpose. This data can be used for both broad and specific uses because it provides a wealth of information that can be applied to various research questions and objectives. Researchers can utilize secondary data to gain insights into a wide range of topics or to address specific research inquiries, depending on their needs. Therefore, the statement that secondary data can be used for both broad and specific uses is true.

Explanation
Internal secondary data refers to the information that is already available within an organization and is collected for purposes other than the current research study. In this case, sales records, invoices, and purchase records are examples of internal secondary data because they are data that have been generated within the organization and can be used for analysis and decision-making. The other options mentioned, such as lamps, desks, chairs, books, magazines, encyclopedias, and external sources like Wikipedia, Google, and Facebook, do not fall under the category of internal secondary data.

Explanation
The correct answer is "Published, syndicated services and databases." This answer is correct because it includes all three sources of external secondary data mentioned in the question. Published sources refer to any information that has been published in books, journals, newspapers, or other media. Syndicated services are companies that collect and sell data on various topics. Databases are electronic collections of data that can be accessed and analyzed. Therefore, this answer accurately identifies the three sources of external secondary data.

Explanation
Books are considered published sources because they go through a formal publishing process before being made available to the public. They are typically written by authors who have expertise in a particular subject and undergo a review and editing process to ensure accuracy and quality. Books are often published by reputable publishing companies and can be found in libraries, bookstores, and online platforms. As such, they are reliable sources of information and are widely accepted as credible references for research and learning purposes.

Explanation
The statement suggests that it is always risky to rely on secondary data. However, this is not necessarily true. While secondary data may have limitations such as potential biases or outdated information, it can still be valuable and useful if properly collected, analyzed, and interpreted. Therefore, the correct answer is False, as it is not always risky to go with secondary data.

Explanation
Secondary data refers to data that has already been collected by someone else for a different purpose. It can be obtained from various sources such as government agencies, research organizations, or published reports. Since secondary data already exists, it is generally less expensive to collect compared to primary data, which requires conducting new research and data collection methods. Therefore, the statement that secondary data is inexpensive to collect compared to primary data is true.

Explanation
Secondary data refers to data that has already been collected by someone else for a different purpose. It can include sources like published reports, government databases, or previous research studies. The statement "Secondary data saves time" is true because using existing data saves the time and effort required to collect new data. Researchers can analyze and interpret the available secondary data instead of starting from scratch, which can be a time-consuming process. By utilizing secondary data, researchers can expedite their research process and focus on analyzing the data rather than spending time on data collection.

Explanation
Secondary data refers to data that has been collected and analyzed by someone else for a different purpose. It may not always be completely reliable as it may be outdated, biased, or collected using different methodologies. Therefore, the statement that secondary data is completely reliable is false.

Explanation
Secondary data refers to data that has already been collected by someone else for a different purpose. It can be obtained quicker than primary data because it is readily available and does not require the researcher to go through the process of collecting data from scratch. Secondary data can be obtained from various sources such as government reports, research studies, and online databases. In contrast, primary data involves collecting data directly from the source, which can be time-consuming and require additional resources. Therefore, the statement that secondary data can be obtained quicker than primary data is true.

Explanation
Survey and observation are both data collection methods. A survey involves gathering information from individuals through questionnaires or interviews to collect data. Observation, on the other hand, involves directly observing and recording behaviors or events to collect data. Watching TV and searching on Google are not data collection methods as they do not involve actively collecting data but rather passively consuming information.

Explanation
To prevent self-selection during a study means to avoid bias or influencing the selection process based on personal preferences or characteristics. It is important to minimize the impact of self-selection as it can lead to skewed results and compromise the validity of the study. By ensuring that participants are randomly assigned or selected in a controlled manner, researchers can minimize the potential for self-selection bias and obtain more accurate and reliable data. Therefore, the statement "You have to prevent yourself from self-selection during a study" is true.

Explanation
In the context of research, the people who respond to a study and become part of the data collection are referred to as the "sample unit." The sample unit is a subset of the larger population that is being studied. It represents the individuals or elements from whom data is collected to draw conclusions about the entire population.

Population: The entire group of individuals or elements that the researcher is interested in studying.

Sample frame: A list or representation of the population from which the sample is drawn.

Sample unit: The individual elements or units selected from the sample frame to be part of the study.

So, when individuals respond to a study, they become the sample unit within the larger population.

Explanation
The statement is false because there are more than three data collection methods that are generally known. Some common data collection methods include surveys, interviews, observations, experiments, and secondary data analysis. Therefore, the correct answer is false.

Explanation
The first step for data collection should be to **create questions**. Before collecting data, you need to define what information or responses you are looking for. Creating clear and relevant questions is essential to ensure that the data you collect will be meaningful and aligned with your research objectives. Tallying and telling the results come later in the data collection and analysis process. Asking the questions follows the creation of questions and is a subsequent step in the data collection process, where you gather responses to those questions.
