Powerpoint for definitions
This document defines and provides examples of key statistical vocabulary:
- Mean is the total divided by how many values there are
- Median is the middle number when values are ordered from smallest to largest
- Mode is the most common value
- Range is the difference between the largest and smallest values
Examples are given to demonstrate calculating the mean, median, mode, and range of a dataset of 5 children's heights.
Powerpoint for definitions
This document discusses key statistical concepts like mean, median, mode, and range. It provides examples of calculating each from a set of children's heights. The mean is calculated by adding all values and dividing by the total number. The median is the middle number when values are ordered from smallest to largest. The mode is the most common value. Range is calculated by subtracting the smallest value from the largest to determine how far apart the values are. Worked examples show calculating each statistic for a set of 5 children's heights.
Analysing our results
This document discusses analyzing test results and different statistical measures including mean, median, mode, and range. It provides examples of calculating each measure and explains when each might be the best measure to use depending on the data set. It discusses situations where the mean could be skewed by outliers and how the median is not affected by outliers. It also includes examples of using a spreadsheet to calculate the mean of a large data set. Finally, it discusses measuring health and fitness through different tests and examples of questions that could be investigated by analyzing class test results data.

Anthropometry in children refers to the measurement of various physical chara...
Height and weight are two fundamental anthropometric measurements used to track a child's growth over time. Height, also known as stature, is typically measured using a stadiometer while the child stands upright without shoes. Weight is measured using a calibrated scale, often with the child wearing minimal clothing. These measurements are plotted on growth charts, which provide visual representations of a child's growth trajectory compared to age- and sex-specific norms.

Magic math
This document provides several methods for multiplying and squaring numbers mentally using tricks and shortcuts:
1) To multiply numbers, multiply the ones digits first, then cross-multiply and add the tens digits, and finally multiply the hundreds digits.
2) For numbers close to 100, subtract the difference from 100 to get the "base number" and multiply the differences.
3) To multiply by 11, add the digits and insert the sum between them.
4) To square a number close to 100, subtract the difference from 100 for the base number and square the difference.
5) Any number ending in 5 is easy to square, as the answer will end in 25.
Amazing trick
This document contains instructions for several math tricks and puzzles. The tricks include multiplying any two-digit number by 11, quickly multiplying two numbers between 11-19 in your head, and squaring 2-digit numbers with specific patterns depending on if they end in 5 or begin with 5. Instructions are also provided for tricks involving birthdays, phone numbers, missing digits, and prime numbers.

Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
