1. D. The chart displays the mean and standard deviations for the data set which is the best measure of central tendency and dispersion/spread respectively for interval/ratio measurement. 2. 97.12 3. The mean baseline depression score is 14.00 and the post test mean depression score for the experimental group is 13.36. This shows that the mean for depression in this group decreased.

Statistics for Business and Economics Personal pre-assignment 1.9 What is a representative sample? What is its value? The representative sample is a subset of a population of interest that is exhibiting the typical characteristics of the population. The most typical way to cover the up-mentioned criterion is the simple random sample which consist of a sample of units that is selected randomly‚ e. g. the sample is selected form the population on a way that every sample of the size is having

dividend discount model ignores capital gains. False‚ the DDM can be decomposed into the capital gain and the dividend yield d) As long as the correlation is below 1‚ the standard deviation of a portfolio is less than the weighted average standard deviation of the individual securities. True‚ can be shown through standard deviation formula 2. Bonds (10%) You have just bought a 3-year 5% annual coupon bond with a face value of €1000. The current discount rate is 10%.

collected the data for each team ’s average attendance for 2003-2005 from an internet site entitled www.baseballreference.com. The summary statistics for this variable show that the mean winning percentage for all MLB teams is 50.4 percent with a standard deviation of 7.6 percent. There is a minimum and maximum of 27 percent and 65 percent respectively. I am taking the log of attendance in order to explain relationships with the independent variables in the form of percent changes in our dependent variable
