1 True
Operationalization is the process of strictly defining variables into measurable factors.
2. while running Descriptive statistics we are most interedted in measures of central tendency and Measures of spread.
Therefore Option 2 is the most suitable choice
3. True

PART B: STATISTICS Question 1. The final exam marks for 10 students taking MPE781 are given as follow: 98 5 8 347 86 7 a) Calculate the mean, median and mode. b) Calculate the first quartile, third quartile, and interquartile range. Interpret these values. c) Calculate the sample standard deviation and interpret this value d) What is the main advantage of the sample standard deviation over the sample variance as a measure of variability?
1. In simple linear regression analysis, we assume that the variance of the independent variable (X) is equal to the variance of the dependent variable (Y) True False 2. The standard deviation of the sampling distribution of the sample mean is the same as the population standard deviation. True False 3. If n=20 and p=.4, then the mean of the binomial distribution is 8 True False 4. If a population is known to be normally distributed, then it follows that...
