Question

choose the most appropriate measure of central tendency (mean, median, mode) and dispersion(range, inter quartiles, standard deviation) and whyd you choose them

a scientist is studying the effect of socioeconomic class on the average family size. while reviewing the distribution of the collected data, the scientist found that a large majority of the families had two or less children while very few families had 5 or more children

Answer #1

most appropriate measure of central tendency is mode

Highest value is 5

we can divide the data into 2 parts

a large majority of the families had two or less children

ery few families had 5 or more children

Data is discrete and has whole number

we can count the number of familes falling in each condition(two or less children) and 5 or more children

measure of central tendency is mode

measure of dispersion is range

WIth histogram we can get frequencies and relative frequencies

Mode

Which measure of central tendency would you use for the
following variables (mean, median or mode). Explain your
choice.
Gender:
Class rank at a college:
Age of high school students:
A skewed income distribution (90% with incomes under $150K; a
few with incomes of several million):

Mean, median, and mode are the three measures of central
tendency that we learned about in this class. We use these to
describe the center of a distribution. For each of the following
examples please identify which measure of central tendency should
be used given the situation.
A negatively skewed distribution
A platykurtic distribution

5.
What measure of central tendency (mean, median, or mode) should you
use if you wish the deviations above the measure to be equal in
size to the deviations below the measure?
