Sample Solution

Relationship between height and weight

Body mass index (BMI, weight/height) is the most widely used weight-height index worldwide. This universal use of BMI assumes that the rationale for its use is universally applicable. BMI is strongly correlated with weight, but is independent of height. Although BMI is highly correlated with weight, there is a significant negative correlation between BMI and weight. In most populations, BMI is not independent of height. Weight does not universally vary with the square of height, and the relationship between weight and height differs significantly between males and females. A person`s height doesn’t dictate their weight, but there is definitely a correlation between the two on average.

nderstand what motivates each individual and implement policies to obtain maximum performance from a group. The importance of the leaders role in motivating individuals is highlighted in Herzberg’s Two Factor theory. The theory highlights factors that must be in place to avoid dissatisfaction, hygiene factors, and factors that promote satisfaction, motivation factors, shown in Figure 4 (Pettinger, 2007). Herzberg’s theory helps to decipher what motivates individuals, but does not advise on how to implement this to produce maximum productivity from an individual, this is achieved by using the theory in conjunction with other motivational theories such as goal setting theory.

Goal setting is not just an important part of motivation, they are essential for both teamwork and successful leadership, they provide indication on what must be achieved, how much effort they must devoted to achieve it and they act as the primary source of job motivation for individuals, therefore setting them accurately is essential (Pettinger 2007). Specific and clear goals are the most effective motivators, and will lead to optimum performance, therefore it becomes essential for a leader to understand what motivates each individual within a group (Pettinger, 2007). Motivation is highly personal, and can differ massively across a group, so the leader must adapt how they motivate to suit each individual, this highlights the need for an organisation to implement policies that allow leaders to be flexible in how they reward individuals. Issues arise when goals are not set well, if the goals are ambiguous, unachievable or too easy then the individual will lose motivation (Pettinger, 2007). Once goals have been set it becomes essential for leaders to regularly assess how individuals are progressing towards them, if well then goals should be made more challenging, if they are struggling then the goals should be made easier. Goals also allow for leader to assess how the team are performing, and how their leadership style is functioning with the group, if goals are not being met the leader must adapt how the team interact together or their leadership
