Question 1

Inferential statistics involve ______ the data.

Accepted Answer

Inferential statistics involve interpreting the data to make inferences or predictions about a larger population based on a sample of data. It involves analyzing the relationships between variables and examining whether any observed differences or relationships are statistically significant.

Question 2

Which of the following would be used to designate the type of statistical methods used to organize and describe the characteristics of a collection of data?

Accepted Answer

Descriptive statistics are used to organize and describe the characteristics of a collection of data, such as measures of central tendency and measures of variability. Inferential statistics, on the other hand, are used to make inferences or generalizations about a larger population based on a sample of data. Sampling methods and population methods are related to how the data is collected, rather than how it is organized and described.

Question 3

Statistics describes a set of ______ that are used for describing,organizing,and interpreting information.

Accepted Answer

Statistics is a field that utilizes various tools and techniques such as graphs, charts, regression analysis, hypothesis testing, and more to help describe, organize, and interpret data. Therefore, choice C - tools and techniques - is the most appropriate response.

Question 4

Which of the following individuals used statistical methods during the 17th century to study the intelligence of his family members?

Accepted Answer

Francis Galton used statistical methods during the 17th century to study the intelligence of his family members, which eventually led to his development of the concept of eugenics. Charles Darwin is known for his contribution to the theory of evolution, Isaac Newton for his contributions to physics and mathematics, and Alfred Binet for his development of the first intelligence test.

Question 5

Once numbers became part of the human language,the next step was to attach ______.

Accepted Answer

Attaching numbers to outcomes was a logical progression in using numbers to quantify and describe results or events.

Question 6

Which of the following is one of the most popular and powerful analytic tools available today?

Accepted Answer

SPSS (Statistical Package for the Social Sciences) is widely recognized as one of the most popular and powerful analytic tools available today, specifically designed for statistical analysis in social sciences. While Microsoft Word and Excel have their uses, they are not dedicated statistical analysis tools, and while Mini Tab is a popular option, it is not as widely used as SPSS.

Question 7

The term used to define a set of tools and techniques describing,organizing,and interpreting data is ______.

Accepted Answer

The set of tools and techniques used to describe, organize, and interpret data is known as statistics. Inference refers to the process of drawing conclusions based on data analysis. Population refers to the entire group of individuals or objects of interest, while sample refers to a subset of the population used in a study. However, statistics is the most fitting choice for the given definition.

Question 8

When humans first realized that counting was a good idea,which of the following became a useful skill for people to have?

Accepted Answer

Collecting information became a useful skill when humans first realized that counting was a good idea, as it involves gathering and keeping track of numerical data or quantities.

Question 9

After the first set of data having to do with populations was collected during the 17th century,scientists needed to develop ______.

Accepted Answer

Scientists needed to develop specific tools to answer specific questions related to the newly collected population data in order to analyze and interpret it effectively.

Question 10

Today,statisticians in many different professional areas find themselves using ______ techniques to answer different questions.

Accepted Answer

Statisticians across various professional fields often use the same statistical techniques to answer different questions, as these foundational methods can be applied universally to analyze data, regardless of the specific area of study.

Question 11

______ is to a smaller group of data as population is to a larger group of data.

Accepted Answer

Sample is a smaller group of data that is taken from a larger group called population.

Question 12

What type of statistics involves collecting,organizing,and summarizing data?

Accepted Answer

Descriptive statistics involves collecting, organizing, and summarizing data. It includes measures such as mean, mode, median, standard deviation, variance, etc. Experimental statistics involve designing experiments to test hypotheses, while inferential statistics involves making predictions and generalizations about a population based on a sample. Organizational statistics is not a recognized type of statistics.

Question 13

What will you need to complete most statistical analyses?

Accepted Answer

Most statistical analyses can be completed on a personal computer with statistical software installed.

Question 14

In which century did the first collection of a set of data pertaining to populations occur?

Accepted Answer

The first collection of data pertaining to populations occurred in the 17th century, when John Graunt published his landmark work "Natural and Political Observations Made upon the Bills of Mortality." This work analyzed death records in London in the 1600s and is considered one of the first examples of demographic analysis.

Question 15

______ statistics are often (but not always)the next step after you have some basic understanding of data.

Accepted Answer

Descriptive statistics simply describe and summarize data, whereas inferential statistics are used to make inferences and draw conclusions about a larger population based on a sample of data. Typically, inferential statistics require a bit more advanced knowledge and techniques than descriptive statistics. Therefore, inferential statistics are often the next step after gaining some basic understanding of data through descriptive statistics. Experimental and observational statistics are types of study designs, rather than subsets of statistics themselves.

Question 16

What type of descriptive statistic is also referred to as the average?

Accepted Answer

The mean is often referred to as the average, and is a type of descriptive statistic that represents the central tendency of a set of data.

Question 17

Your professor tells you,"If you don't start with reliable data,you'll end up with unreliable results." You interpret this to mean which of the following?

Accepted Answer

This phrase is often used in the context of data analysis to emphasize the importance of starting with accurate and reliable data to ensure the validity of any conclusions drawn from the analysis.

Question 18

The term used to describe the science of organizing and analyzing information to make the information more easily understood is ______.

Accepted Answer

Statistics is the science of organizing, analyzing, and interpreting data to make the information more easily understood.

Question 19

The type of descriptive statistic that tells you the most popular or most frequent choice from a selection of choices is the ______.

Accepted Answer

The mode is the type of descriptive statistic that tells you the most popular or most frequent choice from a selection of choices.

Question 20

Descriptive and inferential statistics work cooperatively,and which one you use and when depends on ______.

Accepted Answer

The choice of whether to use descriptive or inferential statistics depends on the specific question that you want to answer. Descriptive statistics are used to summarize and describe the characteristics of a set of data, while inferential statistics are used to draw conclusions or make predictions about a larger population based on a sample of data. Therefore, the question you want answered should guide your choice of statistical method.
