Birth to 48 mouths: Girls and boys Length- for –age and Weight-for age percentiles. Introduction. My objective is to asses’ children’s growth rate by comparing it against the national average. Name | Age in months | height in (CM) | Perntiles | James Ball | 48 | 108 | 90 | Keith Hall | 48 | 105 | 95 | Nathan Hebdidge | 36 | 95 | 50 | Wayne Kerr | 20 | 81 | 25 | Andrew Liddle | 30 | 89 | 25 | Matthew Perters | 15 | 76 | 90 | Kyle Powell | 30 | 94 | 40 | David Wilson | 27 | 88 | 25 | Mark Smith | 42 | 96 | 10 | Skye Wheeler | 30 | 95 | 95 | Beverly Seymer | 24 | 90 | 90 | Courtney Salmon | 35 | 94 | 50 | Elizabeth Pearce | 18 | 78 | 25 | Chloe Marshall | 24 | 86 | 50 | Amy Large | 33 | 96 | 80 | Rebecca Jones | 12 | 74 | 50 | Alexandra Cannon | 34 | 90 | 20 | Amy Sharpe | 12 | 71 | 18 | To achieve my objective’s that are set above. I will have to look at and compare 18 children 9 girls and 9 boys. To gain a fair sample I will choose the children at random and have a range of children aged form birth to 48 mouths. Using the information given on; age, height I will plot where the individuals sit on a national percentile chart from this I will create a table and charts from which it will be possible to get the calculations using equations and checks, mean, mode and median and range. Once I have this information I will compare similarities and differences brining into account influences such as inherited and diet as well as the nature
