It is a process of getting information from a proper subset of population
sampling
Choosing of respondents or subjects from a large population to answer your research questions
sampling
an aggregate or a set of all units/cases (may be people, things, events, etc.) being studied having at least one common characteristics.
population
a big group of people from where you choose the sample
population
“a smaller (but hopefully representative collection of units from a population used to determine truths about that population” (Field, 2005)
sample
a chosen set of people to represent the population
sample
randomly selected subgroup of people or objects from the overall membership pool of a define target population
sample
the number of respondents/subjects that you are going to use in the study
sample size
could be gotten through the use of Slovin’s Formula ( n= N/ 1 + Ne^2 )
sample size
used to compute for sample size
SLOVIN’S FORMULA
used when you have limited information on the characteristics of the population and are using non-probability sampling procedure
SLOVIN’S FORMULA
each member of the defined population has an equal chance of being selected
PROBABILITY SAMPLING
gives the researcher the opportunity to assess sampling error
PROBABILITY SAMPLING
a type of sampling in which all members of the population are given a chance of being selected.
scientific sampling
a method of choosing samples in which
ALL THE MEMBERS OF THE POPULATION are given EQUAL CHANCE TO BE SELECTED as respondents.
SIMPLE RANDOM SAMPLING
a method of selecting every nth element of the population.
SYSTEMATIC RANDOM SAMPLING
after the size of the sample has been determined, the selection of the sample follows.
SYSTEMATIC RANDOM SAMPLING
a probability sampling option where the population is broken down/ separated into strata like segments or sections
STRATIFIED RANDOM SAMPLING
refers to the procedure of collecting, measuring and analyzing accurate insights for research using standard validated techniques.
data collection
Researchers can evaluate their hypothesis on the basis of collected data.
data collection
the primary and most important step for research, irrespective of the field of research.
data collection
varies, depending on different fields of study, depending on the required information.
data collection
A tool used to collect, measure, and analyze data related to your research interests.
Research Instrument
• Pros: In-depth and a high degree of confidence on the data J
• Cons: Time consuming, expensive and can be dismissed as anecdotal
In-Person Interviews
• Pros: Can reach anyone and everyone - no barrier
• Coms: Expensive, data collection errors, lag time
mail surveys
• Pros: High degree of confidence in the data collected, reach almost anyone
• Cons: Expensive, cannot self-administer, need to hire an agency
phone surveys
• Pros: Cheap, can self-administer, very low probability of data errors E
• Cons: Not all your respondents might have an email address/be on the internet, they may be wary of divulging information online.
