A one-page CAPS Grade 4 Maths poster on data handling (Data), with the key ideas, key words and a tip to remember.
Data is information we collect. A tally chart records each answer with a stroke. Every fifth stroke crosses the four before it.
A frequency table shows how many times each answer happens. Add the frequencies to find the total.
Bus 9, walk 12, car 4
9 + 12 + 4 = 25 learners
A pictograph uses a symbol for a number of things. Read the key first. Half a symbol is half of that number.
Cats: 3 symbols = 12 pets
Dogs: 1 and a half symbols = 6 pets
The mode is the number or item that appears most often.
Marks: 6, 8, 7, 8, 9, 8
The mode is 8. It appears 3 times.
To compare two sets of data, add each set to find its total. Subtract to find how many more.
Team X: 3 + 4 + 2 = 9 goals
Team Y: 2 + 2 + 3 = 7 goals, so X has 2 more.
