Part 1: Analysis with Galton’s original data set Galton’s work on children and parents’ height was published in: Galton, F. (1886): “Regression towards mediocrity in hereditary stature”, Journal of the Anthropological Institute, 15: 246-63.

Calculate the normal range by creating the interval that is within 2 standard deviations of the population mean. Multiply the population standard deviation by 2 and then add/subtract from the population mean.
Unit 4 Discussion – Am I Normal? The average height for all males is 69.3 inches with a standard deviation of 2.8 inches. For females, the average height is 64 inches and the standard deviation is 2.8. These are population values. For this week’s discussion, you will calculate a z-score based on your own height […]
Compare the mean vs. the median and discuss what this says about the shape of the variable’s distribution. Interpret the standard deviation (describe what the standard deviation measures and what it tells you about your variable).
Statistics (3pts) Using question 14 (Q14) [How would you best identify yourself politically?]: (a) Create a frequency table that shows counts/frequencies. Include a column count total. Remember, Categories and titles should be correctly labeled (that is, categories should not be labeled “1”,”2”,”3”, etc). (b) Draw a bar chart for this distribution. Remember, Categories and titles […]
