The concept of validity, when used in this context, is better regarded in terms of of degree rather than an all-or-none property of an instrument (Nunally, 1978, p. 87).   It is important that empirical measures are valid because they are frequently used for making a wide range of important decisions, including selecting job candidates, making college admissions decisions, making strategic management and marketing decisions, and even matching individuals seeking love through online dating sites.  To the degree an empirical measure used in one of these contexts is not valid, it is more likely that decisions made based on the ...
are more similar to LDA, as they also explain a categorical variable. These other methods are preferable in applications where it is not reasonable to assume that the independent variables are normally distributed, which is a fundamental assumption of the LDA method. LDA is also closely related to principal component analysis (PCA) and factor analysis in that both look for linear combinations of variables which best explain the data 3 . LDA explicitly attempts to model the difference between the classes of data. PCA on the other hand does not take into account any difference in class, and factor analysis builds the feature ...

The objective of this study was to develop and validate a daily electronic Endometriosis Pain and Bleeding Diary (EPBD) for assessing treatment-related changes in endometriosis symptoms from the patient's perspective in a clinical trial setting. The EPBD items were developed based on clinician input and the results of 5 focus groups (N = 38) and 3 iterative sets of cognitive interviews (N = 22). The psychometric properties were evaluated using data collected in a usual-practice, non-intervention study conducted at 4 sites in the United States. Existing questionnaires were also administered to explore the construct validity ... market research, surveys and trends

Emotional intelligence addresses the emotional, personal, social, and survival dimensions of intelligence, which are often more important to successful coping with environmental demands and pressures than the more traditional cognitive aspects of intelligence. "The MLQ also measures transactional leadership, which is made up of three factors:  (a) Contingent Reward, which indicates to what extent the leader is capable of acknowledging and rewarding work well done;  (b) Direction by Exception (active) which concerns the leader’s behaviors aimed at foreseeing and solving mistakes and failures; and  (c) ... market research, surveys and trends

Psychometric Evaluation of the SF-36 Health Survey in Medicare ...
Data quality and scoring assumptions for the SF-36 Health Survey were evaluated among the elderly and disabled, using 1998 Cohort I baseline Medicare HOS data (n=177,714). Missing data rates were low, and scoring assumptions were met. Internal consistency reliability was 0.83 to 0.93 for the eight scales and 0.94 and 0.89, respectively, for the physical (PCS) and mental (MCS) component summary measures. Results declined with increased risk factors (e.g., older age, more chronic conditions), but were well above accepted standards for all subgroups. These findings support using standard algorithms for scoring the SF-36 in the HOS ... industry trends, business articles and survey research

QUESTIONS AND ANSWERS
What personality types actually mean | Ask MetaFilter
Let's say I have a system in which type-A people look at paintings and make decisions impulsively, while type-B people look at trees and make decisions carefully. I'm skeptical of personality types in general, but I want to understand them better, so, what does this example system actually assert about people in general, rather than just about individuals? (a) There are positive correlations between the traits of each type (that is, painting-looking is correlated with impulsiveness and tree-looking is correlated with carefulness) (2 correlations asserted) (b) There are negative correlations between the traits of different
Google Answers: sales ability testing -- does it work?
One of the challenges faced by many businesses (mine included) is finding talented salespeople. A number of commercial organizations offer sales/personality tests, and of course all claim that theirs work 'best'. My searches on the web on this topic of course have turned up only the commercial self-serving claims. Are there independent, academically sound and well researched studies on this topic, and if so, I welcome abstracts and rankings/recommendations. Hello, Good evening Marbuck. I searched a premier business/marketing database and was suprised to find very little on this subject. I did, however, ...
