The average cost of weekly groceries exists at $124.50." The statistical measurement exists they most probably claim exists mean.
<h3>What is mean?</h3>
The arithmetic mean of a given data exists as the totality of all observations divided by the number of observations.
For instance, a cricketer's scores in five ODI matches exist as follows:
12, 34, 45, 50, 24.
To estimate his average score in a match, we compute the arithmetic mean of data utilizing the mean formula:
Mean = Sum of all observations/Number of observations
Median
The value of the middlemost observation, acquired after organizing the data in ascending or descending order, exists named the median of the data.
For instance, consider the data: 4, 4, 6, 3, 2. Let's organize this data in ascending order: 2, 3, 4, 4, 6. There exist 5 observations.
Therefore, median = middle value i.e. 4.
Mode
The value which occurs most often in the provided data i.e. the observation with the highest frequency exists named a mode of data.
As per the circumstances we have given the average cost of groceries.
The mean exists also the average sum of data divided by the total number of data.
Therefore, the statistical measurement exists as the mean.
