3.1 Measures of central tendency and position

In this task, we will work with the measures of central tendency and position. You will determine the central trend measures for populations and samples, both for ungrouped data and for pooled data. In addition, you will interpret the measures of central tendency and the measures of position of a population or sample. You must read the material presented in sections 3.1 and 3.4 of the textbook to perform the exercises assigned for this activity, with which your learning will be evaluated. You must present the necessary processes to support the response of the exercises and round the final resultsnot the intermediate values that appear during the calculationsto two (2) decimal places, when necessary.

Part I

1. It presents a situation of daily living where you have used some of the measures of central tendency.

Part II

1. It explains the concept of bias, related to the mean, fashion and median.

Part III

1. Will it do you something to calculate the mean and median of a qualitative variable? Explains.

Part IV

1. With the data below, calculate the mean, fashion and median: 77, 98, 87, 111, 95, 93, 88, 90, 62, 71, 99.

Part V

1. Find the first and third quartile for week-long temperatures in the summer of last year, expressed in degrees Fahrenheit: 96, 94, 93, 88, 97, 96, 87.

Parte VI

1. Below is a table of frequencies. Calculate the mean, fashion and median.
