A way to organise data into a table showing how often values occur
The value that appears most often
Look for the highest frequency, then find its corresponding value
The average - total divided by count
∑(Value×Frequency)Total Frequency\frac{\sum(\text{Value} \times \text{Frequency})}{\text{Total Frequency}}Total Frequency∑(Value×Frequency)
To calculate the total for each group
The middle value when data is arranged in order
Locate the middle position in the total frequency
To know how many values there are and find the middle one
The mode - the most common value
Divide total of (value×frequency\text{value} \times \text{frequency}value×frequency) by total frequency
Add frequencies until you reach the median position
