Mean: The maximum value of a series of measurements (or numbers) divided by the number of those measurements.
The definition of the ‘mean’, is an array of numbers added together and then divided by the amount of those numbers. The reason the first definition is incorrect is because it isn’t the maximum value of figures, it’s the total amount added together.
Scientific notation: A notation that represents any number by expressing it as a simple power of ten, using a positive or negative index.
The scientific notation represents any number between 1 and 10 multiplied by a power of 10. This can be done in a positive or negative index. The reason the definition given is slightly incorrect is because it needs to be multiplied by a power of 10 and must be between 1 and 10.
Significant figures: The number of digits you quote when you write down the value of a quantity that has been measured with a degree of uncertainty. The smaller the number of significant figures quoted for a value, the smaller the uncertainty in that value.
The significant figure is the number(s) that carry meaning to that particular range of digits. So in the figure 247300, the most significant number is 2 as it tells us the number is 2 thousand and something. If the figure is not significant then there may be some uncertainty to the last digits there after.
The incorrect definition states that the smaller the number of significant figures quoted for a value, the smaller the uncertainty in that value. It is actually the larger the number of significant figures, the smaller the uncertainty in that value.
TMA 01 – Question 3
In this question I will identify the main contributions to the energy balance at the Earths surface and then state the conditions to which the GMST is in a steady state and would rise.
Solar radiation, infrared radiation, atmospheric radiation, convection and latent heat are all energies that contribute to the balance of the Earth’s surface. This
