FULL SOLUTION VERIFIED PASS
◉ Explain what is meant when it is said that "data vary". How does
the variability affect the results of statistical analysis?. Answer:
Saying "data vary" means that the values of the variable change from
individual to individual. In addition, certain variables can change
over time for certain individuals. Because data vary, two different
statistical analysis of the same variable can lead to different results.
◉ The methods of statistics follow a process. Place the processes in
the correct order.. Answer: 1.
Identify the Research Objective
2.
Collect the Data Needed to Answer the Research Question(s)
3.
Describe the Data
4.
Perform Inference
◉ Match each phrase with its definition.. Answer: The values of the
variable name, label, or categorize. In addition, the naming scheme
,does not allow for the values of the variable to be arranged in a
ranked or specific order.
Nominal level of measurement
The values of the variable name, label, or categorize. In addition, the
naming scheme allows for the values of the variable to be arranged
in a ranked or specific order.
Ordinal level of measurement
Allows for the values of the variable to be arranged in a ranked or
specific order. Differences in the values of the variable have meaning,
but a value of zero does not mean the absence of the quantity.
Arithmetic operations such as addition and subtraction can be
performed on the values of the variable.
Interval level of measurement
Allows for the values of the variable to be arranged in a ranked or
specific order. Ratios of the values of the variable have meaning and
a value of zero means the absence of the quantity. Arithmetic
operations such as multiplication and division can be performed on
the values of the variable.
Ratio level of measurement
◉ . Answer: Descriptive
, statistics consists of organizing and summarizing information
collected, while
inferential
statistics uses methods that generalize results obtained from a
sample to the population and measure the reliability of the results.
◉ . Answer: A(n) statistic is a numerical summary of a sample.
A(n) parameter is a numerical summary of a population.
◉ Fill in the blank.
_________ are the characteristics of the individuals of the population
being studied.. Answer: Variables
are the characteristics of the individuals of the population being
studied.
◉ Define statistics.. Answer: Statistics is the science of collecting,
organizing, summarizing, and analyzing information to draw a
conclusion and answer questions. In addition, statistics is about
providing a measure of confidence in any conclusions.
◉ Match each word or phrase with its definition.. Answer: Occurs
when the effects of two or more explanatory variables are not
separated. Therefore, any relation that may exist between an
