Skewness

Median Standard Deviation Skewness Range Minimum Maximum Sum The mean time a shopper is on the Heavenly Chocolates website is 12.8 minutes, with a minimum time of 4.3 minutes and a maximum time of 32.9 minutes. The fact that the mean time on the website (12.8 minutes) is greater than the median time (11.4 minutes) and the value of skewness is 1.45 indicates that the time on the website is skewed to the right. The following histogram provides further evidence of the skewness in the data. H is to g

Applied Finance Assessment I. Introduction “My ventures are not in one bottom trusted, Nor to one place; nor is my whole estate” (Shakespeare et al., 2007, Scene 1 Act 1) This quote discussing the diversification of Antonio’s investments in the first act of Shakespeare’s play “The Merchant of Venice” was written in the 16th century. But it wasn’t until 1952 that Harry Markowitz wrote his paper “Portfolio Selection” that made him “the father of modern portfolio theory”(Markowitz, 1999). Since then

Again, the interquartile range of 47.03 would be a more appropriate measure of variability due to the skewness. Based on the box-plot, extreme values were 380.18 (Star Wars:

data are mean, median, standard deviation, skewness, kurtosis and test for normal distribution of the data. The mean and the median measure the central tendency of the financial data which shows the location or the clustering of the data around a certain central value. The standard deviation measures the dispersion of the data from this central value and the strength of the central tendency can therefore be judged based on the standard deviation. The skewness measures the asymmetry of the probability

Final Project Week 8 College education is an important investment that demands both time and money. Most students depend on college loans to cater for their costs of attendance, including tuition and fees. The lenders expect the students to pay back the loans in full amount after college. However, the ability of the students to pay back the loans is dependent on their success in the job market, particularly their earnings. Some college degrees lead to careers with good pay while others do not. In

Understanding and Exploring Assumptions Assumptions are important, but not in the way; many would think. The term assumption sometimes is associated with the word guess, but that’s not the meaning as it concerned statistics’ to ensure that your data. In the area of statistics ',’ the word assumption signifies completeness of the data collected (Triola, 2008) . The assumption aids the researcher in verifying the data because if the data does not meet the requirement, the researcher must, then treat

INTRODUCTION The dataset used for the project is the German credit dataset that consists of customers’ financial and credit information and the resulting classification of customers as “good” or “bad” credit risks. This is a well-known publicly available dataset containing observations on 20 variables of 1000 past applicants of which 700 are classified as “good” credit risk and 300 are classified as “bad” credit risk. This report lists the detailed steps involved in developing a credit scoring model
