Question

Assume that there are about 520,000 peoples and 120,000 householders in dire dawa city. A
statistician who conducted a statistical analysis about the size family size and monthly income
of dire dawa households collected data only from 24,000 households. The found that the
average following ten questions from

D. The based on the type variable or attribute, the monthly income data to be collected
from sample household?
E. Which sources of data is /are used to collect the necessary data regarding monthly
income of household?
F. Which of the following measurement scale/level will be used to collect monthly income
data of household?
G. If a statistician describes the collected data and uses the result only for dire dawa
households, then the statistical approach used is possibly?
H. If the statistical used this result to generalize for the households in adis abeba or adama
or mekele, then the statistical approach used is possibly?
I. Write the step or stage a statician will probably follow to conduct the above statistical
study?
J. Write at least three methods a statistician will use to collect monthly income data from
sample household ?
K. If your neighbor is a member of the sample for the study, then based on the result of the
study estimate the average monthly income of your neighbor?

Expert Solution

Step 1

A sample survey is a technique to draw inferences about a population that is relatively bigger in size by studying only a few units of it that consists the sample which is drawn from a population that is much smaller in size.

Levels of measurement, also called scales of measurement, tell you how precisely variables are recorded. In scientific research, a variable is anything that can take on different values across your data set (e.g., height or test scores).

There are 4 levels of measurement:

Nominal: the data can only be categorized
Ordinal: the data can be categorized and ranked
Interval: the data can be categorized, ranked, and evenly spaced
Ratio: the data can be categorized, ranked, evenly spaced, and has a natural zero.

Depending on the level of measurement of the variable, what you can do to analyze your data may be limited. There is a hierarchy in the complexity and precision of the level of measurement, from low (nominal) to high (ratio).
