1) Height (Average US male :69.7 inches, 2.8 inch standard deviation; Average US Female: 64.4 inches, 2.4 inch standard deviation)

2) Shoe Size (Average US male :10.5, 1.5 standard deviation; Average US Female: 8.75 (men's size), 1.25 standard deviation)

3) Ring Size (Average US male: Size 9, 1 standard deviation; Average US female: 6, 1 standard deviation)

Measure your height to the nearest half-inch unless you know it. Determine your most commonly used shoe size (using men's sizes). To find ring size, measure the circumference of your ring finger with a slim piece of paper and a ruler or a tape measure ribbon and use the following chart (or if you already know it, use that number):

Size 4: 1 13/16 inches

Size 5: 1 15/16 inches

Size 6: 2 1/16 inches

Size 7: 2 1/8 inches

Size 8: 2 1/4 inches

Size 9: 2 5/16 inches

Size 10: 2 7/16 inches

Size 11: 2 9/16 inches

Size 12: 2 5/8 inches

Size 13: 2 3/4 inches

Size 14: 2 7/8 inches

Then calculate the z-score associated with your three measurements using the above US averages for your gender. Are you above or below average? Then, assuming Normality, use the z-table, an online calculator, or Excel to determine the percentage of people who are smaller than your measurements in all three areas. Add any insights, comments, or personal experience to elaborate on your post. For example, if you are determined to be shorter/taller than average, is this surprising to you based on your experience? Your replies to other students may be comparing your measurements or anything else of relevance.
