Example of Discussion in Lab Report

Here is an extract from a discussion section taken from a lab report. It provides an analysis of customers’ behavioral patterns with an aim to identify smartphone models within a reasonable price to be procured for the company employees.

Discussion

Knowing the time that users spend on their smartphones during the day encourages examining applications that are particularly popular among the target group. Hereby, respondents were asked to name their favourite mobile phone features. As in a number of other studies, text messaging is an unconditionally popular option among respondents (Deloitte Touche Tohmatsu, 2017; Gerber et al, 2009). However, survey revealed an array of other phone options that outnumber messaging popularity by a large margin. Gaming was identified as the most popular among surveyed users. Respondents rated gaming by 2 points on a 10-point scale, where 1 corresponded with the most favourite feature. Accordant to the respondents, camera, internet browsing and social media were much less favorite features in their mobiles.

Subsequent comparison suggests no major difference between Apple iPhone 8 and Samsung Galaxy S8 with regard to application variety. However, there is a significant price difference between models. It means that Samsung is more feasible with regard to the ratio between options and price range.

Survey indicated an interesting trend that is suggested for in-depth examination in further research. In reported study, majority respondents assigned 3.5 to health and wellbeing applications meaning that they have slightly lost in popularity. Wellbeing and health applications are nevertheless much more popular than browsing the internet, media and entertainment options. Popularity of apps concerning health or wellbeing is certainly an exiting trend that requires further study.

In the meantime, it is worth stressing that phones have become very popular with Canadians. An overwhelming majority of Canadians aged between 24 and 29 spend at least one hour a day on their smartphones. While these users prefer iPhone 8, Samsung S8 is considered a more appropriate option with regard to specs, features, and price.

Survey findings indicated mobile application range that is most popular with the target group, which suggests insights into smartphone model to be preferred. According to the study, health & wellbeing related applications are gaining momentum and are more popular with users than web browsing or media sites. This trend indicates major transformations in consumers’ behavioural patterns regarding mobile use.
