Hands And Feet

show continuous sport with master(prenominal) peaks containing the highest absolute frequence at warmness enjoin determine and low frequencies at the primitive origination space esteems. appendage 11-Graph 10 is a relative frequency distribution graph plot with the info obtained for the arse aloofness of young-bearing(prenominal) individuals. It shows that the mass of those sampled had a foundation distance of 23.5-24.5cm and no females sampled had bills dis may than 22.5cm or greater than 27.5cm. The distribution of the data is close a bell shape burn with one brackish peak with the great frequency at middle of the die hard quantitys and the lowest frequencies at the uttermost(a) quantifys. Appendix 12-Graph 11 is a frequency distribution curve plotted with the data for the foot length of male individuals sampled in this investigation. The data illustrates the fact that the legal age of those sampled had a foot length of in the midst of 27.5 and 28.5cm. This figure is excess greater than the average female foot length measurement indicating that in general males devour larger feet than females. The data obtained from males was of a much narrower range (26.5-29.5cm) than females which may indicate less contagious variation. The distribution of data in the graph is one master(prenominal) peak at the middle of the range (27.5-28.5cm) and much dismount frequency at the essential values (26.5-27.5cm and 28.5-29.

5cm) indicating continuous variation. To breach the correlation between foot length and knock over compeer a precise value and therefore define its moment accurately, Spearmans Rank Correlation Coefficient was apply. This statistical technique was carried out by first ranking the data in order of the superior measurements of foot length and hand span, calculating their difference followed by the difference squared between the ranks of the two measurements. These values were utilise in the formula: 1 - 6 x Ã…d2 n(n2-1) to stretch out a numerical value for the correlation and therefore beat its strength, characteristic (i.e. positive or negative) and...If you want to get a full essay, order it on our website: Ordercustompaper.com
