In this assignment I will be explaining the reasons for selecting the particular method of data collection for a selected product/service.
The selected product that I will be collecting data for is an anti-depression medication made my HML (Hutchinsons Medical Limited). The data collecting method I’ve chosen is face to face interviews in order to get the respondents full attention and collect data without any distractions. I intend on finding out the respondent’s age, whether they suffer from depression/anxiety, whether they take medication for their depression/anxiety, and which form of our product they would prefer to purchase (roll on, cream, liquid, pills).
The sampling method that I chose was probability sampling. I chose this method because it means everyone gets the chance to be picked meaning that the results will represent the whole group of interest. Another example of the fairness in this method is someone reaching into a box full of names and picking one out. The selection process ensures that everyone has a chance of winning. The advantages are that it’s not bias and as aforementioned it represents the whole group of interest. The results can also be used to calculate any further statistical analysis.
I rejected non random sampling as it’s an unfair selection process as you get to pick people which makes in an unequal selection process. The people that are picked out might not represent the rest of the group and unlike probability sampling you can’t use the results to calculate any further statistical analysis. Unlike probability sampling, this process takes a lot of time as you’d have to pick the people first which already takes up time before collecting the data you need off them. Another method that I rejected was quota sampling because it’s impossible to find a potential error in sampling as it’s not a random selection. A proportion of the
