Meaning behind Validity and Reliable

Reliability is a characteristic of any computer-related component that consistently performs according to its specifications. Therefore the quality of a computer such as the Apple Mac should be reliable due to its constant software update and the capacity of the computer therefore, you would expect to gain a great quality of work. Furthermore, the meaning behind validity is similar to the reliability however, it is just a main focus on the quality of something rather than focusing on the attributes of a computer related component.

Discuss the advantages and disadvantages of Qualitative Quantitative data.

When discussing the advantages and disadvantages of qualitative and quantitative data we must first identify what each of them are. Quantitative data is (with reference to Google definitions) ‘data expressing a certain quantity, amount or range’. Therefore one advantage of using quantitative data is that it can allow a wide/broad study, which as a result will then enhance the generalisation of the results. This could be displayed in the media industry when looking for a suitable location, meaning instead of look for one location, quantitative data allows you to take into consideration a wider range of locations whether they are based in the same area, country or continent.

 Furthermore, another advantage of quantitative data may be that there is a sense of accuracy within the results, which in return can allow a greater success in achieving the goal/objective. However, as well there being advantages of quantitative data there is also disadvantages, one of which is that the results only consist of numerical values rather that written or narrative results. This can hinder the decision-making, as there is no human perception towards the results.

In addition another disadvantage that may come about when using this techniques is the collection of an inadequate and ostensible database.

In comparison, qualitative data is based around description therefore making it harder to analyse in comparison to quantitative data, this type of research is mostly found in individual observation.

One advantage of using this form of research data is that when this data is used alongside quantitative data there can be an explanation of why a distinctive response was given. Similarly, as well as quantitative data this form of data also has some disadvantages. One of which is that there is a difficulty in making some ‘systematic comparisons’. An example of this is if there is a differentiation in responses that may come across as being biased.

Finally, another disadvantage found in this form of research is that it is rather dependent on the individual doing the research rather than a number of people, this means that the individual must have a high level of skill required to carry out this form of research.
