Measures of Central Tendency and Position

1. Present a daily living situation where you have used any of the measures of central tendency. 2. Explain the concept of bias, related to the mean, the mode and the median. 3. Will it help you to calculate the mean and median of a qualitative variable? Explain 4 . Using the data below, find the mean, mode, and median: 77, 98, 87, 111, 95, 93, 88, 90, 62, 71, 99. 5 . Find the first and third quartiles for the temperatures of a week in the summer of last year, expressed in degrees Fahrenheit: 96, 94, 93, 88, 97, 96, 87. 6. Below is a table of frequencies. Find the mean, mode, and median. Limits Frequencies (f) 110-115 25 116-121 22 122-127 14 128-133 20 134-139 9 140-145 26 146-151 10 7. Below are the weight data (pounds) of a group of babies born at Hospital Auxilio Mutuo last month: 5.8, 6.0, 7.3, 8.1, 6.4, 7.3, 7.1, 6.9, 5.1, 7.2, 6.1, 5.8, 5.7, 6.4, 7.3, 7.0, 7.3, 6.2, 4.8, 5.1, 6.9.
