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
