The 1st individual variable is LOCATION which is a categorical variable. The three subcategories are Urban, Suburban and Rural. Since Location is a categorical variable, the measures of central tendency have not been calculated for this variable. The frequency distribution and pie chart are given as follows:…
The first variable considered is Location, a categorical variable. The three subcategories are Urban, Suburban and Rural. The frequency distribution and pie chart are included. Measures of central tendency and descriptive statistics are not calculated due to the categorical nature of the variable.…

In statistics the final data will be presented in a professional matter. This includes common charts or graphs that present data in percentages and qualities. This helps the viewers see the clean data in details. The basic charts used to present data in statistics are Bar or Pareto graphs and Pie or Circle graphs. Pareto and bar graphs both categorize qualitative data using bar figures to present the bar graph. Pie and circle graphs present qualitative data in a circle or pie figure. Usually…
76% of Naperville students have been alcohol free in the last 30 days. Mr. Baird believes that AP stats students are different.…
If you cannot identify quantitative research studies to critique, you will be unable to complete the Final Paper and therefore may need to select a different topic. Consequently, you are encouraged to search the Ashford University Library for quantitative research studies on your chosen topic to ensure there are enough available for use. For this assignment, include at least one quantitative research study from a peer-reviewed source that was published within the last ten years, cited according to APA guidelines and that supports your chosen topic.…
r2 = fraction of variation in one variable that is explained by least-squares on the other variable…

Data is only as good as the collection and maintenance mechanisms are. Unfortunately, concerns for the validity of the data arose when looking at the experience level of the data collectors, response bias, and using the coin-toss (50/50) method for obtaining direction to travel to each cluster of responses identified in the survey. Ensure both the scientific approach and procedures are well within standard, but also ensure that the common sense factor is considered as well. Sometimes the sensible approach can be lost in the algorithms and…
Typically, there are two general types of statistic that are used to describe data. Measures of central tendency are ways of describing the central position of a frequency distribution for a group of data. Measures of spread are ways of summarizing a group of data by describing how spread of the scores. Week 4’s assignment was to…
Go to the library and find a journal article in your area of interest that contains empirical data, but does not contain any visual representation of the data. Use the data…
Summarizing and Presenting Data If using RES/351 data: Revise the report submitted in Week Two based on the feedback provided by the instructor in the Learning Team assignment, and insight gained by reading. Summarize the data collected using descriptive statistics.…
research studies use two different categories of statistics to analyze the data collected: descriptive and inferential. Descriptive statistics are simply numerical or graphical summaries of data, and may include charts, graphs, and simple summary statistics such as means and standard deviations to describe characteristics of a population…
Descriptive statistics give us a way to sum up and express our data but do not allow one to make a judgment related to ones theory. When delivering a test of diversity there are two primary techniques of sum up the data using descriptive statistics. The primary direction to measure the central tendency for two conditions (mean, median or mode.) The second technique to show date is to calculate and measure dispersion; these measurements will show the extent of a data set. Dispersion can also be measured by calculating the range. The range difference is show in a set of scores by the order of the smallest to the largest.…
