Study Notes

Report Credibility and Structure

  • Credibility: Accuracy, believability, and professional organization of a report are crucial
  • Believability: Clear, logical thinking, precise expression, and accurate presentation are necessary for a believable study
  • Executive Summary: Concise overview of main points; must accurately represent the whole report
  • Introduction: Provides background information for understanding the report
  • Methods/Procedures: Details the research methodology used
  • Limitations: Weaknesses in research methodology that might affect confidence in research conclusions

Data Collection and Analysis

  • Data Validation: Process of verifying survey data accuracy and absence of bias or fraud
  • Curbstoning: Data collection personnel filling surveys for fake respondents
  • Editing: Error checking of raw data from interviewers and respondents
  • Coding: Grouping survey responses and assigning values
  • Data Entry: Inputting coded data into software for analysis
  • Tabulation: Counting observations in categories
  • One-Way Tabulation: Categorizing single variables
  • Cross Tabulation: Categorizing multiple variables simultaneously
  • Mean: Arithmetic average of a data sample; all values summed and divided by the number of valid responses.
  • Median: Middle value in a ranked data set; exactly half of the responses are above and half are below the median.
  • Mode: Most frequent value in a data set
  • Range: Difference between highest and lowest data point
  • Standard Deviation: Average distance of distribution values from the mean
  • Variance: Average squared deviation about the mean of a distribution of values

Statistical Analyses

  • Independent Samples: Two or more groups of responses tested as though they may come from different populations
  • Related Samples: Two or more groups of responses that originated from the sample population
  • ANOVA (Analysis of Variance): Statistical technique to determine if three or more means are statistically different
  • F-Test: Statistical test in ANOVA to evaluate mean differences
  • Follow-up Tests: Identify statistically significant mean differences after ANOVA shows differences
  • N-way ANOVA: ANOVA analyzing multiple independent variables simultaneously
  • Interaction Effect: Effect of multiple independent variables on the dependent variable
  • Perceptual Mapping: Visual representation of product placement on important dimensions
  • T-Test: Hypothesis test utilizing the t-distribution for samples smaller than 30 with an unknown standard deviation

Report Components

  • Appendix: Section for complex, detailed, or technical information supplementing the main report
