鈥淣umber of times per week鈥 is what type of data? a. qualitative b. quantitative discrete c. quantitative continuous

Short Answer

Expert verified
The data is quantitative discrete.

Step by step solution

01

Understanding the Data

First, identify what is meant by 'Number of times per week'. This phrase is referring to a count of something that happens repeatedly within a week. Since it involves counting, it is not a qualitative measure.
02

Identifying Quantitative Data Types

Quantitative data can be either discrete or continuous. Discrete data are countable quantities, often whole numbers, while continuous data are measurable and can take any value within a range.
03

Classification Based on Characteristics

Next, consider whether 'Number of times per week' can only take specific values. Since you can count the occurrences, such as 1 time per week, 2 times per week, etc., and there are no values like 1.5 times per week, it is countable and therefore discrete.
04

Final Determination

Conclude that 'Number of times per week' is quantitative discrete data because it counts occurrences and only whole numbers accurately describe it.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Quantitative Data
Quantitative data refers to any kind of information that can be measured or counted numerically. This type of data is typically expressed in numbers, allowing for mathematical calculations and statistical analysis. Using this data type, one can easily perform operations like addition, subtraction, multiplication, and division.
Quantitative data is crucial in fields such as science, finance, and economics as it allows for data-driven decisions and precise calculations. There are two forms of quantitative data: discrete and continuous, which helps further classify the nature of the data being analyzed.
  • Measurement: Quantitative data often describes quantities, measurements, or counts.
  • Numerical Value: It represents data in a numerical format, making it suitable for various types of mathematical operations.
  • Objectivity: Unlike qualitative data, quantitative data is objective and free from personal bias, leading to more accurate results.
Understanding quantitative data is the foundation for distinguishing between discrete and continuous types.
Discrete Data
Discrete data is a category of quantitative data. It represents data that can take on only specific, separate values within a range. These values are often whole numbers and are countable. An example is the number of students in a classroom鈥攁n actual countable integer that cannot be half or decimal.
In real-life scenarios, discrete data helps when you need precise, integral numbers. It is useful in various applications like user counts, frequencies, and any situation where items can be individually counted.
  • Countable: Discrete data is countable and often involves integers like 1, 2, 3, etc.
  • Fixed Values: It includes fixed values, which do not change continuously over time or intervals.
  • Examples: Examples include the number of eggs in a basket, tickets sold, or goals scored in a soccer match.
Understanding discrete data is pivotal to data classification and helps in identifying the nature of information being presented.
Data Classification
Data classification is the process of organizing data into categories based on its characteristics. Effective classification helps simplify the analysis and handling of data, making it a crucial step in data management.
Data generally falls into two main types: qualitative and quantitative. Further within quantitative, data is divided into discrete and continuous categories. This deeper classification ensures that the appropriate analytical techniques are applied.
  • Purpose: The primary goal of classification is to make data handling more efficient by providing clarity on what type of data you're working with.
  • Processes: It involves identifying data types and organizing them into defined categories.
  • Importance: Proper classification allows for easier understanding, analysis, and communication of data findings.
Grasping data classification concepts is essential for anyone involved in data analysis, as it directly affects the accuracy and relevance of the findings.

Name the sampling method used in each of the following situations: a. A woman in the airport is handing out questionnaires to travelers asking them to evaluate the airport鈥檚 service. She does not ask travelers who are hurrying through the airport with their hands full of luggage, but instead asks all travelers who are sitting near gates and not taking naps while they wait. b. A teacher wants to know if her students are doing homework, so she randomly selects rows two and five and then calls on all students in row two and all students in row five to present the solutions to homework problems to the class. c. The marketing manager for an electronics chain store wants information about the ages of its customers. Over the next two weeks, at each store location, 100 randomly selected customers are given questionnaires to fill out asking for information about age, as well as about other variables of interest. d. The librarian at a public library wants to determine what proportion of the library users are children. The librarian has a tally sheet on which she marks whether books are checked out by an adult or a child. She records this data for every fourth patron who checks out books. e. A political party wants to know the reaction of voters to a debate between the candidates. The after the debate, the party鈥檚 polling staff calls 1,200 randomly selected phone numbers. If a registered voter answers the phone or is available to come to the phone, that registered voter is asked whom he or she intends to vote for and whether the debate changed his or her opinion of the candidates.

For each of the following eight exercises, identify: a. the population, b. the sample, c. the parameter, d. the statistic, e. the variable, and f. the data. Give examples where appropriate. A cardiologist is interested in the mean recovery period of her patients who have had heart attacks.

Is a sample of 500 volunteers a reliable measure for a population of 2,500?

Seven hundred and seventy-one distance learning students at Long Beach City College responded to surveys in the 2010-11 academic year. Highlights of the summary report are listed in Table 1.39. $$\begin{array}{|l|l|}\hline \text { Have computer at home } & {96 \%} \\\ \hline \text { Unable to come to campus for classes } & {65 \%} \\ \hline \text { Age 41 or over } & {24 \%} \\ \hline \text { Would like LBCC to offer more DL courses } & {95 \%} \\ \hline \text { Took D L classes due to a disability } & {17 \%} \\ \hline \text { Live at least 16 miles from campus } & {13 \%} \\ \hline \text { TTook DL courses to fulfill transfer requirements } & {71 \%} \\ \hline\end{array}$$ Table 1.39 LBCC Distance Learning Survey Results a. What percent of the students surveyed do not have a computer at home? b. About how many students in the survey live at least 16 miles from campus? c. If the same survey were done at Great Basin College in Elko, Nevada, do you think the percentages would be the same? Why?

A 鈥渞andom survey鈥 was conducted of 3,274 people of the 鈥渕icroprocessor generation鈥 (people born since 1971, the year the microprocessor was invented). It was reported that 48% of those individuals surveyed stated that if they had $2,000 to spend, they would use it for computer equipment. Also, 66% of those surveyed considered themselves relatively savvy computer users. a. Do you consider the sample size large enough for a study of this type? Why or why not? b. Based on your 鈥済ut feeling,鈥 do you believe the percents accurately reflect the U.S. population for those individuals born since 1971? If not, do you think the percents of the population are actually higher or lower than the sample statistics? Why? Additional information: The survey, reported by Intel Corporation, was filled out by individuals who visited the Los Angeles Convention Center to see the Smithsonian Institute's road show called 鈥淎merica鈥檚 Smithsonian.鈥 c. With this additional information, do you feel that all demographic and ethnic groups were equally represented at the event? Why or why not? d. With the additional information, comment on how accurately you think the sample statistics reflect the population parameters.
