The theory or model upon which the student’s investigation is based is described and the link to the student’s investigation is explained. The Independent and Dependent Variables are stated and operationalized in the null or research hypotheses. Exploration Level Descriptor The research design is explained. The sampling technique is explained. The choice of participants is explained. Controlled variables are explained. The choice of materials is explained.
Key: Yellow = Near verbatim usage between group members Key: Blue = Can be similar but definitely should not be verbatim between group members (example – Identifying the key study or theory) D. Explain the choice of participants . 1. Did you allocate participants into groups? Why? 2. State relevant characteristics of sample and explain relevance E. Explain controls that were used. 1. State your controlled variables and explain why/how they were controlled a) Situational controls b) Participant controls c) Experiment controls F. Explain how materials were developed and why you made the choices that you did . G. Describe your procedure, including how ethical standards were met . 3) ANALYSIS A. No raw data is displayed here, but it is in the appendix. B. You can reference raw data here by citing it in the appendix section using Roman numerals (for example “see Appendix I”). 1. Nominal Data – “Yes/No”, “Male/Female” binomial data 2. Ordinal Data – Data can be put in order or ranked 3. Interval Data – is ordinal data but with standardized differences between any values, for example mph . C. This Analysis section should be subdivided with the following titles - “ Descriptive statistics ” and “ Inferential Statistics ” D. Apply your analysis of descriptive statistics in the correct section: 1. Median and interquartile range often go well together 2. Mean and standard deviation often go well together 3. Highlight the variability and spread of data using one measure of central tendency a) Mean - The mean is simply a numerical average. b) Median - the value that lies in the center of the distribution. c) Mode - The mode is the value that occurs most frequently.
