Henri was tasked to study variable stars, whose luminosity differed over time.
To see the gender difference on the study variable findings showed that female scored high on both rumination and depression.14
As a single descriptive study, Level VI data were obtained (Polit & Beck, 2012); data obtained provided the ability to correlate each study variable.
Where l22 represent population correlation coefficients between y and x, Where l40 = b2(y) and l04 = b2(x) were the kurtosis for the population of the study variable and the auxiliary variable respectively.
Generally, the correlation coefficients found were low, the highest being between the dependent study variable (GOODWIMP) and the LEV variable (57.8%), although it was not significant.
Table 4: Mean, standard deviation and t-value for male and female among study variable (N = 220).
Prior to analyses, 228 surveys, for which the test respondent failed to complete all items on any given study variable, were removed; the resulting final sample size was 1,432, for a completion rate of 86.3%.
Compare the mean and standard deviation for each study variable. If a variable is measured on a unidirectional scale using low-to-high positive integers, such as 1 to 5 (as opposed to a bidirectional scale using minus-to-plus integers such as -3 to +3 with zero in the middle), and its mean is less than twice its standard deviation, the variable's underlying frequency distribution is likely asymmetric, suggesting that the mean is neither a typical nor representative score (Altman & Bland, 1996).
The topic they wanted to investigate or the main study variable was what effect abuse--either heard or witnessed--had on male and female children.
In estimation of population parameters like mean, total, and ratio, the auxiliary information is some time incorporated with the study variable to improve the efficiency of the estimators.
The opportunity has therefore been taken to observe CQ Cep in order to investigate the utility of the telescopes to study variable stars and to see whether the observations can be used together with eclipsing binary star modelling software to investigate their physical attributes.
