What Random experiment is
A random experiment is a process or set of steps that produces a result that cannot be predicted with certainty. It is a type of scientific experiment that is conducted with the aim of determining the probability of certain outcomes. The process of a random experiment typically involves the following steps:
-
Identify the possible outcomes of the experiment. These outcomes could be qualitative or quantitative.
-
Select a process or method of generating the random result. This could involve using random number generators, shuffling a deck of cards, or rolling dice.
-
Collect data from the experiment. This could involve counting the number of times a particular outcome is generated, or measuring the values of the outcomes.
-
Analyze the data collected to determine the probability of each outcome occurring. This could involve calculating the probability of each outcome using the relative frequencies of the outcomes.
-
Draw conclusions from the data analysis about the probability of the outcomes occurring. This could involve discussing the implications of the experiment and its results.
Examples
- Estimating the probability of a coin landing on heads after flipping it a number of times.
- Investigating the effect of a new advertising campaign on sales.
- Investigating the effect of two different fertilizers on the growth of a plant.
- Measuring the average weight of a population of mice.
- Comparing the effectiveness of two different types of medical treatments.
