Solved by verified expert:Central Tendency and VariabilityUnderstanding
descriptive statistics and their variability is a fundamental aspect of
statistical analysis. On their own, descriptive statistics tell us how
frequently an observation occurs, what is considered “average”, and how
far data in our sample deviate from being “average.” With descriptive
statistics, we are able to provide a summary of characteristics from
both large and small datasets. In addition to the valuable information
they provide on their own, measures of central tendency and variability
become important components in many of the statistical tests that we
will cover. Therefore, we can think about central tendency and
variability as the cornerstone to the quantitative structure we are
building.For this Discussion, you will examine central tendency
and variability based on two separate variables. You will also explore
the implications for positive social change based on the results of the
data.To prepare for this Discussion:Review this week’s Learning Resources and the Descriptive Statistics media program.For additional support, review the Skill Builder: Visual Displays for Categorical Variables and the Skill Builder: Visual Displays for Continuous Variables, .Review the Chapter 4 of the Wagner text and the examples in the SPSS software related to central tendency and variability.From
the General Social Survey dataset found in this week’s Learning
Resources, use the SPSS software and choose one continuous and one
categorical variable Note: this dataset will be different from your Assignment dataset).As you review, consider the implications for positive social change based on the results of your data.Post, present, and report a descriptive analysis for your variables, specifically noting the following:For your continuous variable:Report the mean, median, and mode.What might be the better measure for central tendency? (i.e., mean, median, or mode) and why?Report the standard deviation.How variable are the data?How would you describe this data?What sort of research question would this variable help answer that might inform social change?Post the following information for your categorical variable:A frequency distribution.An appropriate measure of variation.How variable are the data?How would you describe this data?What sort of research question would this variable help answer that might inform social change?Be
sure to support your Main Post and Response Post with reference to the
week’s Learning Resources and other scholarly evidence in APA Style.
