Research Question

What is the correlation between homeless individuals and their association to a mental health problem
and does this cause people at risk of homelessness to use substance abuse?

Sample size and sampling techniques
The sample size of the study is calculated using Slovin-Yamane formula with 95 percent
confidence level. The targeted population of my study is 68,000. The mathematical formula of
Taro Yamane is presented as follows:
𝑛=

𝑁
1 + 𝑁 (𝑒)2

Where:
𝑛 = 𝑇ℎ𝑒 𝑟𝑒𝑞𝑢𝑖𝑟𝑒𝑑 𝑠𝑎𝑚𝑝𝑙𝑒 𝑠𝑖𝑧𝑒
𝑁 = 𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑝𝑜𝑝𝑢𝑙𝑎𝑡𝑖𝑜𝑛 (𝑝𝑢𝑏𝑙𝑖𝑐 𝑠𝑒𝑟𝑣𝑎𝑛𝑡𝑠 𝑖𝑛 𝐾𝑒𝑛𝑦𝑎)
𝑒 = 𝑀𝑎𝑟𝑔𝑖𝑛 𝑜𝑓 𝑒𝑟𝑟𝑜𝑟 (𝑖𝑛 𝑝𝑒𝑟𝑐𝑒𝑛𝑡𝑎𝑔𝑒)

Substituting numbers in Yamane’s formula:
𝑛=

68000
1 + 68000 (0.05)2

𝑛 = 397.664808
𝑛 (𝑅𝑜𝑢𝑛𝑑𝑒𝑑 𝑢𝑝) = 398
After calculating the sample, after substituting the numbers into Taro Yamane’s formula, a
sample size of 398 individual was obtained

In identifying subjects who will complete the questionnaire, stratified sampling and purposive
sampling will be employed.
Stratified random sampling technique will be used in categorizing individuals, who took part in
the survey, into different levels of status i.e those who are employed and those that are
unemployed. Therefore, the two strata for this study will be employed and unemployed.
Opinions from all individual from both levels are reproduced in the sample for the study.
Purposive sampling technique to identify the four cities in Texas state where the study was to be
conducted such cities are; Austin, Dallas, San Antonio and Houston. Then the data collected on
the correlation of homeless individuals and their association to a mental health problem from
these cities can be extrapolated to the entire United State of America, hereafter then stratified
sampling technique will be employed to categorize the individuals into the different levels before
the questionnaire is administered to them.
