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
