3.6.2 Correlation Analysis Correlation analysis is one of the data analysis method use in quantitative research when researchers intended to examine the relationship between both variables (Research Methodology‚ n.d.). The Pearson’s Moment Correlation Coefficient (PMCC) ranges between +1 and -1.If the coefficient value is +1 and -1‚ it is an indication that the relationships between both variables are strong. A value of +1 indicate that there is a positive relationship between variables‚ means that

amount of life insurance per household in the United States is $110‚000. This distribution follows the normal distribution with a standard deviation of $40‚000. A. If we select a random sample of 50 households‚ what is the standard error of the mean? U=110‚000 S=40‚000 N= 50 SE = s/ sqrt (n) = 40000/ sqrt (50) = 5656.85425 The standard error of the mean is 5656.85425 B. What is the expected shape of the distribution of the sample mean? The expected shape of the sample mean will be the bell shaped

Dear Dr. Ducking I am still not able to afford a book at this time. Also I did not make time to use the book in the reading room and the library only had the 3rd edition of the book. So I wrote a summary of the class notes that you had put up on blackboard. Chapter 3 Summaries: Chapter 3 talks about descriptive statistics with numerical measures. These measures consist of location and variability. The measures of locations are mean‚ median‚ mode‚ weighted mean‚ geometric mean
