A computer program randomly sampled ordered pairs of scores from known populations that departed from bivariate normal form and calculated correlation coefficients from sample values. Hypotheses were tested (1) that population correlations are zero using the t statistic; and (2) that population correlations have non-zero values using the r to z…

Nearly half of all faculty members taught summer school last year, according to a "Chronicle" survey. Figures were for faculty members of all ranks and those without academic ranks. The disciplines with the most faculty members teaching were business/economics and physical education. (MLW)

A review of articles that report study results based on couple samples indicated response rates are rarely high enough for statistical inference. Four procedures that can be used to compensate for insufficient response rates (collecting information from nonparticipants, census comparisons, adjustment in analysis, and replication) are examined.…

The worries & wishes of 14 -19 years-old adolescents of Abadeh, Bavanat & Khorambid cities in the north of Fars province are investigated in this research.

This Digest describes matrix sampling of test items as an approach to achieving broad coverage while minimizing testing time per student. Matrix sampling involves developing a complete set of items judged to cover the curriculum, then dividing the items into subsets and administering one subset to each student. Matrix sampling, by limiting the…

The purpose of the current study was to investigate the effectiveness of four methods of handling missing data. Effectiveness was defined as the probability of reproducing the covariance matrix of the target sample accurately. Effectiveness of the missing data methods was assessed by manipulating the proportion of cases containing missing values…

This Digest describes four types of errors in mail surveys and summarizes the ways they can be reduced. Any one of these sources of error can make survey results unacceptable. Sampling error is examined through inferential statistics applied to sample survey results. In general, increasing sample size will decrease sampling error when simple…

Article presented a list of questions designed to learn from the school trustee how effective his role in developing educational objectives is. (RK)

It is the purpose of this paper to provide social scientists with some insight in dealing with Type 11 error, that is, the probability of failing to reject a false null hypothesis, and therefore, optimum sample size and number of levels, in the random-effects analysis of variance. (Author/RK)

The purpose of the present study is to provide some facts on the morbidity risk and incidence of enuresis in Icelandic children, aged 5-15 years, and to study its association with some mental and environmental variables often related to this symptom. (Author)

The purpose of this study is to examine the SACU variables in relation to other commonly used variables in predicting university success in Alberta. (Author)
