According to the research findings, when dealing with two different groups within a population, the most appropriate sampling method to use is the stratified sampling method. Specifically, this technique is a modification of simple either random or systematic sampling styles, where the population is divided into two homogeneous subgroups. Afterward, the sample is selected using either of the techniques mentioned above. In applying these techniques in the given case, first I would divide the groups into male and females. For instance, if there are men 1800 men and that of females are 900. Carrying out the systematic sampling for the males would be 20 (n) = 1800 and female would be 10 (n) = 900. In my estimate, the number of men makes up two-thirds of the population and females equal to one-third of the population; therefore, sampling technique applied, in this case, is called a proportional stratified sampling method. The eleven threats to internal validity are Selection, Maturation, History, Subject Effect, Instrumentation, Treatment Replication, Subject Attrition, Presenting, Statistical Regression, Diffusion of Treatment, and Experiment Effect. A true experimental design compares two identical groups of randomly picked participants, and that is the experimental group and the control group. The experimental group is subjected to a certain intervention (s) while the control group is used to assess the changes in the experimental group. Specifically, the control group gives the validity of the research by confirming that the changes experienced or because of the intervention and not any other factor.

Symptom assessments may be different in many ways even if there were having the same effects because of many factors though in their management, the stages of infections and the wishes of the patients must be taken into consideration. This is because in considering the symptoms in a patient, there are various practices, which may not be culturally acceptable, such issues are majorly known if the patient reveals to the medical practitioner.
Lastly, Sample 4 has a maximum percentage retention value of 51.36 under 0.125mm sieve aperture.
The distribution of the sieve aperture in every sample was different. In sample 1 the concentration of the distribution of percent retained is mainly on 0.25 to 1.00 mm, sample 2 and 3 have the same concentration from 0.125 to 0.50 mm while in sample 4, the concentration of the distribution is on 0.125 to 0.25.
