VARIANCE STABILIZING TRANSFORMATION OF THE STEPPED-UP RELIABILITY COEFFICIENT1

A SIMPLE METHOD OF CALCULATING THE COEFFICIENT OF CORRELATION

Where two sets of measurements can each be grouped into below average, average and above average classifications with an equal number assigned to each of the below average and above average classifications, a 3 by 3 table can then be tabulated with frequency counts. The exact value of the product moment coefficient of correlation can then be calculated very simply by means of the formula, r = (DIFF)/2m, where DIFF is the difference between the sum of the corner numbers on the positive diagonal and the sum of the corner numbers on the negative diagonal, and m equals the number in each of the below average and above average classifications for each variable. The formula for r is applicable to negative as well as positive correlation.

AN INTERPRETATION OF LIVINGSTON'S RELIABILITY COEFFICIENT FOR CRITERION-REFERENCED TESTS

An alternative interpretation of Livingston's reliability coefficient is based on the notion of the relation of the size of the reliability coefficient to the range of talent. It is shown that the (generally) larger Livingston coefficient does not imply a smaller standard error of measurement and consequently does not imply a more dependable determination of whether or not a true score falls below (or exceeds) a given criterion value.

JOURNEYING AS RELIGIOUS EDUCATION: THE SHAMAN,THE HERO,THE PILGRIM,AND THE LABYRINTH WALKER

In this article the author looks at the image of journey and its archeform, quest, and finds two spiritual concepts: that of movement to the center followed by a return, and the concomitant understanding that all that has arisen and reached maturity must return to renew itself. Four journeys, the shamanic journey of soul, the hero's journey of spirit, the pilgrimage of community, and the allegorical journey of the labyrinth, are viewed from this persepctive. These journeys are formulated into a context of myth, ritual, symbol, and story which places them at the heart of religious education as bearers of religious tradition and meaning.
