Final answer:
Tyler and Morgan develop their theories using qualitative data, such as in-depth interviews and focus groups. This data helps build robust discussions and predictions, while also ensuring their theories align with tested observations and can result in precise models and laws if experiments are controlled.
Step-by-step explanation:
Tyler and Morgan base their theories on data that includes in-depth interviews, focus groups, and the analysis of content sources. This type of data collection falls into the realm of qualitative research. Qualitative data provides a good foundation for discussion and prediction, offering insights into the subject matter that may not be immediately apparent through quantitative data. In their research, they also likely consider observations that have been consistently tested and attributed to a cause to ensure their theories are supported by reliable information, as in the case of the cause-and-effect relationship demonstrated by 'fire causes burns'. Additionally, as researchers become more systematic in their exploration, they may use rigorous methodologies to gather data, possibly performing controlled experiments, to develop well-founded models, theories, and laws.
Data plays a crucial role in scientific inquiry, acting as the observations collected in a scientific investigation to test hypotheses. It is vital that these observations fit our intuition and stand up to scrutiny against basic equations and established knowledge to accurately describe nature and human experiences.
