Instructions:

In this task, you will work with measures of central tendency and position. You will determine the measures of central tendency for populations and samples, both for ungrouped data and for grouped data. In addition, you will interpret measures of central tendency and measures of position of a population or sample. You should present the processes necessary to support the answers to the exercises and round the final results not the intermediate values that appear during the calculations to two (2) decimal places, when necessary.

Part I

1. Present a situation of daily living where you have used any of the measures of central tendency.

Part II

1. Explain the concept of bias, related to the mean, the mode and the median.

Part III

1. Will it help you to calculate the mean and median of a qualitative variable? Explain

Part IV

1. Using the data below, find the mean, mode, and median: 77, 98, 87, 111, 95, 93, 88, 90, 62, 71, 99.

Part V

1. 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
