Organising raw data into frequency tables, including grouped data for larger ranges.
Where your child meets this in real life: Summarising survey results, organising test scores, or analysing data
SEAGReady breaks create frequency tables into 2 steps, taught in order so each skill builds on the last.
Create a frequency table from raw data by counting occurrences of each distinct category or value
Create a grouped frequency table for numerical data by assigning values to given class intervals
Three free sample questions from our create frequency tables course. Every question comes with a full explanation, and hints that guide without giving the answer away.
Miss Kelly asked her P6 class to name their favourite colour. The results were: blue, red, blue, green, red, blue, red, green, blue, red, green, blue. How many children chose blue?
Answer: A. 5
Go through the list systematically and cross off each 'blue': blue (1), red, blue (2), green, red, blue (3), red, green, blue (4), red, green, blue (5) Blue appears 5 times.
Stuck? Start here: Go through the list and cross off each 'blue' as you count it.
Mr Murphy recorded spelling test scores: 45, 67, 72, 38, 55, 81, 63, 49, 76, 58. Which group does the score 55 belong in?
Answer: A. 50-59
The groups are: 30-39, 40-49, 50-59, 60-69, 70-79, 80-89. 55 starts with 5, so it belongs in the 50s group. 55 is between 50 and 59, so it goes in the 50-59 group.
Stuck? Start here: Look at the first digit of 55. It starts with 5, so it's in the 50s.
Aoife collected data about pets in her class. The results were: dog, cat, dog, fish, cat, dog, cat, cat, fish, dog. She made this frequency table: | Pet | Frequency | | Dog | 4 | | Cat | 4 | | Fish | ? | What number should replace the question mark?
Answer: A. 2
Count the fish in the data: dog, cat, dog, fish (1), cat, dog, cat, cat, fish (2), dog Fish appears 2 times. Check: 4 + 4 + 2 = 10, which matches the 10 items in the data.
Stuck? Start here: Count how many times 'fish' appears in the original data.
This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.
Mrs O'Neill asked her P6 class to name their favourite sport. The results were: football, GAA, football, swimming, GAA, football, GAA, swimming, football, GAA, swimming, football.
Create a frequency table to show how many children chose each sport.
Step 1 of 5
Mrs O'Neill asked her P6 class to name their favourite sport. The results were: football, GAA, football, swimming, GAA, football, GAA, swimming, football, GAA, swimming, football.
Create a frequency table to show how many children chose each sport.
The frequency table shows football was most popular with 5 votes.
The key insight: Always check your frequencies add up to the total number of items in your data!
Watch out: Football: 4, GAA: 5, Swimming: 3. Miscounting happens when you don't cross off items. Go through the list carefully and mark each one.
These are the misconceptions we see most often in create frequency tables, including the ones our practice questions are specifically designed to catch.
Struggling with create frequency tables? The real gap is often in one of these earlier topics.
SEAGReady finds the exact step where your child gets stuck, teaches it with worked examples like the one above, and brings it back for review so it sticks.
