Calculating the Mean from a Frequency Table: Multiply each value by its frequency, add these results, then divide by the total number of entries.

Finding the Median with Frequency Table: Use the formula (N + 1) / 2 to locate the median position in an ordered list. For example, if N is 15, the median is the 8th value in the frequency table.

Identifying the Mode in a Frequency Table: The mode is the value with the highest frequency.

Calculating the Range: Subtract the smallest value from the largest value in the table.

Effect of Outliers on Mean vs Median: Outliers can skew the mean, making it less representative, while the median is more stable and reflects the centre of the dataset reliably.
