2 Kinds of Research related to nursing
- Nursing Research
- Research in Nursing
-more broader study in the profession
-focus more on issue (e.g. historical, educational, etc) that can affect nursing profession
e.g. Nursing education in PH
Research in Nursing

Convenience / Accidental Sampling
everybody has chance to become a sample
e.g. Fish Bowl Method
Simple Random Sampling
create strata (characteristic) of the population and divide the population into homogenous group
-basis of same group: characteristics
> E.g. you decided to group a population into male and female
Grouping: gender
Characteristic: male or female
Stratified Random Sampling
successive random sampling of units
- big group without distinct characteristic
> E.g. you decided to group a population into schools / barangay
Grouping: school / barangay
Characteristic: None
Cluster Sampling
get a proportion of the population
Quota Sampling
samples are handpicked by researchers
Purposive/ Judgmental Sampling
networking or referral system
Snowball Sampling
– kth of the list
Formula: k= N/n
N= population size
n= sample size
Systematic Sampling
SLOVIN’S FORMULA
n = N / 1 + Ne^2
N =population size e=margin of error
