The subjects were 65 girls between the ages of 14 years, zero months and 14 years, six months. All of the subjects were enrolled in required physical education classes at Glenbard East High School, Lombard, Illinois. Following the selection of the subjects, the investigator administered the various anthropometric measurements, motor ability tests and reaction-movement measures used as data for this study all subjects were measured and tested by the writer, thus eliminating the probable differences that would occur if several persons were involved in collecting the data. Seven anthropometrical characteristics, four motor ability tests and eighteen reaction-movement times were recorded for each subject. The mean and standard deviation were derived for each of the variables and a t test to determine the significance of the difference between the means of certain of the reaction-movement tests was computed. Zero-order coefficients of correlation were also computed for all combinations of the twenty nine variables. The computations derived by using the t test technique to ascertain the significance of the difference between the means of certain of the reaction-movement tests indicated that of the twenty eight t results, seventeen were significant at the one per cent level and two were significant at the levels between two and five per cent, the nine t results that did not indicate a significant difference in the mean scores, were all comparisons between the subject’s initial, actual and completion times for a particular body component in both, the dominant and non-dominant test phase. The zero-order coefficient of correlation technique was employed to study the relationships between certain anthropometrical characteristics and certain meter abilities; certain anthropometrical characteristics and certain reaction-movement measurements; and certain motor abilities to certain reaction-movement measurements. Twenty-eight coefficients of correlations were computed between the anthropometrical characteristics and motor abilities measured in this study. Only seven were significant at the five per cent level and all indicated a low relationship. One hundred and twenty six coefficients of correlation were derived between anthropometrical characteristics and reaction-movement measures. Five were positive correlations and two were negative correlations at the five per cent level. All indicated low relationships. The computation of coefficients of correlation between the motor abilities measured in this study and the reaction-movement measures indicated that twenty seven correlations out of seventy two were significant at the five per cent level. All of them were negative and revealed low relationships. The above correlation results indicated that there was little relationship between the anthropometrical, motor and reaction movement variables measured in this study.M.S. Ed. (Master of Education
