Descriptive statistics: What do all of those numbers mean in terms of the problem. Organizing and summarizing data is called descriptive statistics. Two ways to summarize data are by graphing and by using numbers (for example, finding an average). A statistical graph is a tool that helps you learn about the shape or distribution of a sample or a population. Our data is examining the distance (miles) between twenty retail stores, and a large distribution center The Mean: (84.05 miles) shows the arithmetic mean of the sample data. Standard E: (7.71822 miles) shows the standard error of the data set, which is the difference between the predicted value and the actual value. Median: (86.5 miles) shows the middle value in the data set, which is the value that separates the largest half of the values from the smallest half of the values Mode: (96 miles) shows the most common value in the data set. Standard [: (34.51693 miles) shows the sample standard deviation measure for the data set. Sample Va: (1191.418 miles) shows the sample variance for the data set, the squared standard deviation. Kurtosis: (-0.48156 miles) shows the kurtosis of the distribution. Skewness: (0.210738 miles) shows the skewness of the data set’s distribution. Range: (121 miles) shows the difference between the largest and smallest values in the data set. Minimum: ( 29 miles) shows the smallest value in the data set. Maximum: (150 miles) shows the largest value in the data set. Sum (1681 miles) adds all the values in the data set together to calculate the sum. Count (20 miles) counts the number of values in a data set.

What is descriptive statistics? What is inferential statistics? Why do we care about the level of measurement of a variable? Why do we use n-1 rather than n in calculating sample variance? What are confounding variables, and what effect do they have on assessing cause-and-effect relationships? When would you prefer median to mean as a measure of central tendency? Why don’t we just sum the deviations from the mean to measure dispersion of a variable? When is it legitimate to...

List three types of descriptive -statistics- commonly used in research. Why do we use descriptive statistics in both descriptive methods research and experimental methods research? Why are descriptive statistics so important in quantitative research? Could we do quantitative experimental research without descriptive statistics? If so or not, why or how? What are your thoughts given what we are learning?

Match the terms with their definitions. Paired sample T test, Inferential statistics, descriptive statistics, Non-parametic inferential statistical procedures, Chi-square, Correlation, Independant-samples T test, Parametric inferential statistical procedures 1) This parametric statistical procedure is used when you have a dependent variable that is interval (1, 2, 3, 4, .....and so on), and an independent variable that is dichotomous (1=yes, 2=no for example). This tests compares the means (averages) of two samples and tells you if there are statistically significant differences between...

I am curious as to how the "descriptive and inferential statistics physically mean and how they are used in a simulated "real-world" problem" portion should be answered. I spent a long time trying to come up with a way to solve this. Don't be shy. All ideas are welcome.
