Given the following set of data, demonstrate that subtracting a constant (e.g., 5) from every score reduces all measures of central tendency by that amount.
Answer to relevant QuestionsGiven the following data, show that multiplying each score by a constant multiplies all measures of central tendency by that constant. Create a boxplot for the variable ADDSC in Appendix D. These data are available at https://www.uvm.edu/~dhowell/fundamentals8/DataFiles/Add.dat. Calculate the range, the variance, and the standard deviation for the data that Katz et al. collected on SAT performance after reading the passage. In Exercise 5.2, what percentage of the scores fall within two standard deviations from the mean? Unfortunately, the whole world is not built on the principle of a normal distribution. In the preceding exercise the real distribution is badly skewed because most children do not have language problems, and therefore ...
