The correct answer is fixed-interval
In a fixed interval reinforcement scheme, the reinforcement is presented if the organism emits at least one response after a fixed time interval. Generally, this scheme is represented, placing the specific value of the fixed interval. For example: FI-1 hour means that the backup is presented after 1 hour and only for the first response issued.
The fixed interval reinforcement scheme results in a low frequency of responses at the beginning of the interval, increasing as the end of the interval approaches.

Example: When a farmer is going to measure the whole years production its not possible by using the formula of mean. Because it involves various kind of data.
Explanation:
In statistics, three basic component is mean, median and mode.
- Mean refers to the average of the whole data.
- Median refers to the intermediate value of the full range.
- Mode refers to the number repetition of a particular number in a set.
For e.g. Mean implies its importance mainly in climatological data, score based data.
Median easily provide the required value in height and weight of students.
Mode provides right value when same price/kilo is repeating in case of two different product.
