Social Design


Experimentaldesign shall be used in the evaluation of the hypothetical scenario.The reason for using the model is that it is considered as the goldstandard and provides the base against which other designs areevaluated. The design is also reputable for providing internalvalidity. This is the approximate truth about conclusions of thecause –effect relationships between variables. In addition,experimental designs are described as the best for studying theeffects of social programs (Donovan &amp Hoover, 2013).

PartA: Critique

Thefirst change would be to explain the degree to which the cause andeffect relationship applies to the variables. This involves addingstatistics that can be measured to obtain a similar outcome (Edwards,1968).&nbsp The hypothesis states that severe stress can lead to heart failure.The word “can” indicates chances that an event will happen. Thehypothesis does not indicate the exact probability that someone withsevere stress will have heart failure (Donovan &amp Hoover, 2013).

Further,it does not provide whether there is equality in the sample used.People are said to be different and will handle stress differently.It should specify the kind of persons who are likely to experienceheart failure as those composed of the sample (Donovan &amp Hoover,2013).

Thethird change would be to include the details about the correlationsbetween severe emotional stress and heart failure. Correlation can bepositive, negative or have no correlation at all. A positivecorrelation occurs when the two variables move in the same direction.For example, heart failure increases or decreases when emotionalstress increases or decreases respectively. In contrast, a negativecorrelation exists where two variables move in opposite direction atany point in time, which means that an increase in one variablecauses a decrease to the other (Trochim, 2006). For a nocorrelation, one variable might increase as the other stagnates ordecreases explaining no relationship between the variables. It shoulddemonstrate whether the chances of heart failure increase asemotional stress increases or does it reduce.

PartB: Correlation analysis

Acorrelation study on the relationship between heartbreaks and thedescription that they are fatal and incurable can be tested byadjusting the link between the variables (Trochim, 2006). Forexample, when one experiences heartbreak from the loss of a relativeor someone they were so attached and connected can be defined asfatal. However, the degree of “fatal” depends on the level ofattachment and the burden of loss. Further, the level of fatalnesswill differ from one individual to the other (Yin, 2003). There arethose that will get emotional like crying and it takes them centuriesto believe that the loved one passed on. In contrast, others willaccept it as God’s doing and move on with their lives (Trochim,2006). Similar, is a heartbreak from lack of employment, the degreeof fatalness will differ&nbspfrom one person to the other based ontheir level of&nbspattachment. Other people will prefer becomingself-employed after a long period of disappointment.

PartC: Experimental study

Thehypothesis “Beta blockers are effective in treating heartbreaksepisodes” can be tested using the experimental design by assumingtwo groups of patients suffering from the heartbreaks episodes(Trochim, 2006). They should have similar backgrounds and symptoms ofheartbreaks episodes. One group is treated using beta-blockers whilethe other is treated using other means like counseling. Theobservations should indicate that patients treated with beta blockersheal much faster compared to counseling. The efficacy of the medicineshall be related to how well it works in practice.
