Research Investigation on Human Traits
Parts of a Research Investigation ArticleTitle: Descriptive title about what you did and found (we’ll do this last).
Introduction: Paragraph introducing different types of human traits (inherited vs. acquired, dominant vs. recessive) and overall purpose of the experiment. The last sentence should be your hypothesis (what you think you will find). Dominant traits are more common than recessive traits.
Methods: Paragraph explaining what you did and how you analyzed the data.
Data & Results: In this part you show your data (graphs, tables, pictures, etc) and EXPLAIN your data. For example: “Graph 1 shows that 93% of CORE is right-handed”.
Analysis and Conclusions: One or more paragraphs analyzing your data and explaining WHY might have gotten those results. The last paragraph should sum up what you did and what you found (now you can write your title!)
Comparing Traits Survey Data
In order to compare traits survey data between your class and your family, it’s helpful to convert our frequency data into percentages (since the total number of the class is much higher than your family). Create a new data table for comparing your data. Convert frequency data into percentages and add to new data table.
