3.2. Data Source, Population, and Sample
3.2.1. Data Source
Data source are all information or subjects that should be collected and 
chosen by the research (Arikunto, 1998:114). There are two kinds of data, 
primary and secondary data
.
It is called as primary data when the data are 
directly taken as a result of collecting the data individually and it is an 

---

original data from the source. On the other hand, secondary data is 
obtained from the second hand.
In this study, the writer uses primary data. The writer collects the data 
directly from the research subject. The data of this research are taken from 
Billboards installed in Semarang as outdoor advertisement.
3.2.2. Population
Arikunto (1992:107) says that if the object of a research is less than 
a hundred, it is better to take all of them into account, so that the research 
is called population research. However, if the object is larger than a 
hundred, we may take some of them in a percentage.
Population is a group of individuals with determined quality and 
characteristics. In the other words, population is the entire group from 
which the sample is chosen (Hadi in Setyaning, 2006). Populations of this 
research are all the words in the billboard installed in Semarang as outdoor 
advertisement.
3.2.3. Sample
Sample is a part of population that will be analyzed in the research 
(Arikunto, 1997:104). The sample which is used in a research should 
represent the population of the research.
Samples are taken from the population according to particular 
criteria based on the purpose of the research. In determining the sample, 
the writer uses purposive sampling method. Mardalis, (2003:58) says that 
purposive sample method is a method in which the chosen samples have to 

---

be able to represent the population. The sample of this research is the 
word or term in billboard installed in Semarang as outdoor advertisements 
which contain word formation.
