Exam Tips for Frequency Tables
- Always check totals - frequency column should add up to total number of data values
- Use tally marks correctly - groups of 5 with the 5th mark crossing the first 4
- Choose appropriate class widths - usually 5, 10, or another round number
- Be careful with inequalities - understand ≤ and < symbols for grouped data
- Label clearly - include units and clear headings
- Modal class vs mode - modal class is a range, mode is a single value
- Show working - especially when calculating from frequency tables
