Figure 4.3. Sample Sizes
According to the findings from Figure 4.3, the main sampling range used in the English education research reports is 31-100 samples 37.27, which are
followed by 11-30 samples 34.55, 101-300 samples 6.36, and 1-10 3.64 respectively. According to the results of the present study, the number of
research reports conducted with the participation of 301-1000 samples is 0.91 lower than the others. There are 19 research reports which are not reported the
sample sizes 17.27.
9. Sampling Technique
In determining the number of people in population as the subjects selected, a research needs to select characteristics of the population which are represented
in the sampling technique. In qualitative approach, the aim of sampling is not to generalize to a population, but to develop an in depth exploration of a central
phenomenon. While, in quantitative approach, the aim is to generalize from individuals selected to a population. Therefore, the trends of the classification of
the sampling techniques can be seen from the following Table 4.13.

Table 4.13 presents the number and percentages of the sampling techniques used in the research reports. The most frequent investigated sampling
technique is Purposive Sampling 17.27= 19 research reports. Random Sampling 9.09= 10 research reports is in the second most frequently
investigated. Cluster Sampling and Non-Probability Sampling Volunteer has a balance distribution 1.82 = 2 research reports. The least percentage are
Convenience Sampling, Random – Purposive Sampling, Cluster – Random
Sampling, and Representative Sampling 0.91 = 1 research report. Accordingly, there are 71 research reports which are not presented the sampling
techniques.
10. Validity
During the process of collecting and analyzing data, the findings and the interpretation of the research should be accurate. Therefore, researchers needs
validating findings to determine the accuracy or credibility of the findings through some strategies in validation techniques. The Table 4.14 would represent the
variety of the validation types occurred. PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI
