NAME: Exploring Relationships in Body Dimensions TYPE: Observational SIZE: 507 Observations, 25 Variables DESCRIPTIVE ABSTRACT: This dataset contains 21 body dimension measurements as well as age, weight, height, and gender on 507 individuals. The 247 men and 260 women were primarily individuals in their twenties and thirties, with a scattering of older men and women, all exercising several hours a week. SOURCE: Measurements were initially taken by the first two authors - Grete Heinz and Louis J. Peterson - at San Jose State University and at the U.S. Naval Postgraduate School in Monterey, California. Later, measurements were taken at dozens of California health and fitness clubs by technicians under the supervision of one of these authors. VARIABLE DESCRIPTIONS: Columns Variable Skeletal Measurements: 1 - 4 Biacromial diameter (see Fig. 2) 6 - 9 Biiliac diameter, or "pelvic breadth" (see Fig. 2) 11 - 14 Bitrochanteric diameter (see Fig. 2) 16 - 19 Chest depth between spine and sternum at nipple level, mid-expiration 21 - 24 Chest diameter at nipple level, mid-expiration 26 - 29 Elbow diameter, sum of two elbows 31 - 34 Wrist diameter, sum of two wrists 36 - 39 Knee diameter, sum of two knees 41 - 44 Ankle diameter, sum of two ankles Girth Measurements: 46 - 50 Shoulder girth over deltoid muscles 52 - 56 Chest girth, nipple line in males and just above breast tissue in females, mid-expiration 58 - 62 Waist girth, narrowest part of torso below the rib cage, average of contracted and relaxed position 64 - 68 Navel (or "Abdominal") girth at umbilicus and iliac crest, iliac crest as a landmark 70 - 74 Hip girth at level of bitrochanteric diameter 76 - 79 Thigh girth below gluteal fold, average of right and left girths 81 - 84 Bicep girth, flexed, average of right and left girths 86 - 89 Forearm girth, extended, palm up, average of right and left girths 91 - 94 Knee girth over patella, slightly flexed position, average of right and left girths 96 - 99 Calf maximum girth, average of right and left girths 101 -104 Ankle minimum girth, average of right and left girths 106 -109 Wrist minimum girth, average of right and left girths Other Measurements: 111-114 Age (years) 116-120 Weight (kg) 122-126 Height (cm) 128 Gender (1 - male, 0 - female) The first 21 variables are all measured in centimeters (cm). Values are separated by blanks. There are no missing values. STORY BEHIND THE DATA: The first two authors investigated the correspondence between frame size, girths, and weight of physically active young men and women, most of whom were within normal weight range. One goal of this investigation was to develop predictive techniques to assess the lean/fat body composition of individuals. PEDAGOGICAL NOTES: These data can be used to provide statistics students practice in the art of data analysis. Such analyses range from simple descriptive displays to more complicated multivariate analyses such as multiple regression and discriminant analysis.
