Professional Research and Communication Assignment: Data Analysis

This assignment solution addresses key concepts in professional research and communication, focusing on data analysis and survey interpretation. The document examines the validity of survey data, highlighting potential biases and suggesting improvements to data collection methods, such as using interval data instead of ordinal data. It also explores the limitations of online surveys, considering factors like participant engagement and the potential for biased responses. The solution then delves into different types of data (nominal, interval, and ratio), providing examples and distinctions between them. Finally, the document analyzes various research methods (descriptive non-experimental, quasi-experimental, and experimental studies) to determine the most suitable approach for testing a given hypothesis, emphasizing the importance of experimental studies for establishing causality. The solution draws on several academic references to support its claims.
