Are instances where interviewees are hostile to the interviewers based on race, clture or even personal feelings (Tarantino & Peary,1998, p 65-70). Te main purpose of the research is mainly to define effect the expectations would have on the performance of the children in the reading test. Tis is a mental hypothesis; icrease in the performance of the children with increased expectation in the reading test. Te dependent variable within the research is the performance of the prevailing children and it is measurable. It is mental since it is on the expectations expected of the two groups of children in the reading test.

Tis is a one-tailed directional hypothesis because there is a difference between the scores of the two groups and it is expected that Mr. Witebeards class would score less than Mrs. Mllet’s class (GREENE & DOLIVEIRA, 2006, p 19-20). Te control group in the experiment is Mr. Te purpose of this control group is to determine the consequentialism of the mind-set expectations of students. Te independent variable is the expectation in the performance (GREENE & 2006, p 23-30).

Ech individual researcher contributes in all conditions and thus smaller number of researchers is required for the process. Tis is applicable in cases where it is expensive to run everyone in the tests. Te individual variances are visible and can be explained since the effects of the free variables are clearly visible. Tere is ease in the separation of the orderly individual variances from the effects of free variables. Sores are greater for each participant and thus the influence of the free variables on the dependent can be deduced.

I is uneconomical to use this technique where there are a small number of participants since they require twice the number of participants as required in the repeated measures design to obtain the same amount of information. I is applicable, dverse and flexible. I is application in a vast range of set ups since it can take many forms from the informal approaches to the complex and structured standardized approach. I therefore yields both quantitative and qualitative data. I is the only form of research where cause and the effects of behaviors can be known.

Tis is because it involves the use of variables manipulatively to determine what variable causes what effect on what variable. Oservation uses mechanical equipment that enables the collection of massive quantities of data...
