Impact of Social Media on Body Dissatisfaction

Study 1

Notes

A study was conducted to find the impact of social media on body dissatisfaction among college students between the ages of 18 and 25.

Description of Everything Observed or That Can Be Remembered

In this study, a simple random sampling technique was performed at a Saudi Arabia (King Saud University) university, and 204 participants were obtained. The students in the study who met the inclusion criteria were randomly selected, and informed consent was obtained before participation in the research.

Analysis

Simple random sampling is a type of probability sampling whereby every member has an equal opportunity to get selected for the sample. This study’s sample size was 204 instead of 232, which was the originally intended number (Alruwayshid et al., 2021). Most participants were females, and more than half ranged from age 21 to 22.

Reflection

A university generally has a huge number of students; therefore, 204 might not be considered big enough to be representative of the population.

Study 2

Notes

The second study focused on how television, social media, and peers influence body dissatisfaction, life satisfaction, and eating disorder symptoms among adolescent girls between the ages of 10 and 17.

 Description of Everything Observed or That Can Be Remembered

This study made use of snowballing, which is a non-probabilistic sampling technique. 237 participants were sampled from a local and university community (Ferguson et al., 2014). The participants in the study were mainly Hispanics and all of them were females.

Analysis

Even though snowballing is considered non-random, it effectively reaches underrepresented groups or subgroups, facilitating a more heterogeneous sample.

Reflection

Like the previous study, the sample size used in this study was also small, hence reducing the power of the study.

READINGS

Goldilocks sampling

As indicated in your reading, a sample consists of the people you collect data from. A sample is smaller than the population but should be representative of the population.
Sampling is selecting people from the population to participate in the research study. When sampling, you want a large enough sample to ensure the representation of characteristics reflective of the larger population. That means that the larger the sample, the more people from the population will be included. However, the larger the sample, the more time-intensive and cost-prohibitive data collection will become. But, if your sample size is too small, you run the risk of not having a representative sample, hindering the generalizability of your study.

Just like Goldilocks, you need to have a sample that is “just right.” Your text discusses the importance of reviewing relevant literature (i.e., studies similar to yours) to help determine the appropriate sample size. Another good rule of thumb, also mentioned, is having 30 participants in each group (I.e., experimental and control).

Sampling Techniques
There are two overarching types of sampling: probability and nonprobability sampling. The most commonly used sampling techniques discussed in your text include random sampling, stratified random sampling, and cluster sampling. These three sampling techniques are grouped under probability sampling because all members of the identified population have an equal chance of being selected for the sample.
Convenience and quota sampling fall under the nonprobability sampling type because all members of the identified population do not have an equal chance of being selected for participation in the sample.
Once you have identified your sample, you must know how to collect data from them.
