Part 1: Discussion Question
An important component to quantitative research is choosing the correct statistical test. The
University Library offers several Sage Research Methods resources to help you in your endeavors.
Using the “Sage Tools – Which Stats Test?” link from the University Library and your chosen
variables, complete the “Which Stats Test?” survey to decide which statistical tests could be most
beneficial to understanding the relationship between your variables.
Write a 250- to 300-word response to the following:
•
•
Discuss the process of choosing a statistical test using the tools from Sage and your Salkind
& Frey (2019) text.
Explain what impact variable types have on statistical tests.
Part 2: Student Responses
Student response 1:Review the classmates’ posts and respond to at least one in a
minimum of 150 words. Explain why you agree or disagree. Then, share an example from
your professional experience to support your assertions.
The levels of measurement show the method for classifying a specification. Each represents a
characteristic that differs by whether it is a degree of something and how specialists interpret
the magnitude. The nominal level indicates one where no feature is higher or lower than
another, like a gender, where men and women are distinct types of people, and none is more
advantageous. The ordinal one also states non-numerical characteristics but mentions ranks;
an example might be the Likert scale, where there are the lowest and highest positions. The
other two levels of measurement are where changes are quantifiable (Norman, 2010).
The interval level of measurement identifies degree standards where a change of one unit
signifies the same in all, regardless of the stated number. Nevertheless, unlike the ratio, it does
not have an absolute bottom level. An example is a date, where a difference of one day is
always equal to 24 hours, but the year 0 does not denominate an absence of an aspect.
Researchers can utilize such numbers for additions and subtractions. However, they cannot
utilize such variables as multipliers because scholars solely find differences (Allanson & Notar,
2020).
The ratio level of measurement compares a quantity with a size worth one unit. Time length is
an example of a continous variable that enters into this category. When an entity tells how long
something took, it divides the amount by a standard such as the second, a day, or one year,
among many others. A discrite variable that enters into this level of measurement might be the
population size, as zero inhabitants signify there are no items in thst location. Unlike the
interval level, it can be multiplied or divided, and specalists can note a real absence.

The process of choosing a statistical test can be difficult, and there are many factors to
consider. The type of data, the research question, and the type of analysis are all important
factors. In, general, quantitative research is concerned with relationships between variables,
and the type of statistical test used will be determined by the type of variables involved (Salkind
& Frey, 2019).
There are two main types of variables: categorical and continuous. Categorical variables are
those that can be divided into groups, and they are often used to represent characteristics like
gender or ethnicity. Continuous variables are those that can take on any value within a range,
and they are often used to represent things like age or income.
The type of statistical test used will be determined by the type of variables involved. For
example, if the research question is concerned with the relationship between two categorical
variables, then the chi-squared test would be used. If the research question is concerned with
the relationship between a categorical variable and a continuous variable, then the t-test would
be used.
The independent variables chosen are race (nominal) and healthcare accessibility (ordinal). The
dependent variable is the mortality rate (ratio). The suggested test is ordinal regression. Ordinal
regression is a member of the family of regression analysis. As a predictive analysis, ordinal
regression describes data and explains the relationship between one dependent variable and
two or more independent variables.
The impact of variable types on statistical tests is that the type of statistical test used will be
determined by the type of variables involved. Categorical variables are often used to represent
things like age and income. The type of statistical test used will be determined by the type of
research question being asked.
