A sample is the participants you select from a target population (the group you are interested in) to make generalisations about.

• A sample is the participants you select from a target population (the group you are interested in) to make generalisations about.
• Representative means the extent to which a sample mirrors a researcher's target population and reflects its characteristics.
• Generalisability means the extent to which their findings can be applied to the larger population of which their sample was a part.
• A Volunteer sample is where participants pick themselves through newspaper adverts, noticeboards or online.
• Opportunity sampling, also known as convenience sampling, uses people who are available at the time the study is carried out and willing to take part. It is based on convenience.

The random sampling method is one of the simplest and most common forms of collecting data as it is meant to provide an unbiased representation of a group. The random subset of selected individuals is used to represent an entire data set.

• The goal of simple random sampling is to create a manageable, balanced subset of individuals that is representative of a larger group that would otherwise be too challenging to sample.

POWER ENERGY

• POWER ENERGY

Energy is the ability to perform work. Energy can neither be created nor destroyed, and it can only be transformed from one form to another. The unit of Energy is the same as of Work, i.e. Joules. Energy is found in many things, and thus there are different types of energy.

• All forms of energy are either kinetic or potential. The energy in motion is known as Kinetic Energy, whereas Potential Energy is the energy stored in an object and is measured by the amount of work done.
