Sampling strategy - Assignment ExampleIn other words, each fraction of the population has an equal chance of becoming part of the sample size. This strategy shall be used to use up fifty (50) of such new mothers. The rationale for using ergodic sample distribution technique in the denary survey and selecting fifty (50) respondents is that surveys require the collection of selective information from a relatively larger setting and as such the sample size must be large enough to give a full-strength proportionate representation of all people within the population.For the qualitative focus group study, a goal-directed sampling strategy shall be used to select members in the sample size. A purposive sampling strategy do not allow for equal probability of selection of members but comes with its own reward which is, a specific classification of respondents who are thought to be suitable for the provision of certain data will be selected (Bushman, 2007). This is ideal for a focus grou p study because using a random strategy may include members who do not qualify for the variables set out to achieve the intend focus. Because the focus group will be critically analyzed, a fewer number of respondents of ten (10) shall be included. Generally for the focus group, the inclusion and exclusion criteria shall be based on a group of closely defined variables, whereby only new mothers who fall within the variables shall be included (Calfee and Scheraga, 2004). A typical mannikin of such variable could be new mothers who had pre-mature child birth.Bushman, B.J. (2007).
