Practice Tally Chart in Statistics
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
A tally chart is a simple way to record and count data using vertical strokes called tally marks. Every fifth mark is drawn diagonally across the previous four, making groups of five that are easy to count. For example, |||| represents 4 and ⧸|||| represents 5.
Tally charts are like counting on your fingers, but on paper. Every time something happens, you draw a line. Cross every fifth line to make counting by 5s easy - like bundling sticks.
Example 1
easyA class voted for their favourite colour. The tally marks show: Red |||| ||, Blue |||| , Green |||, Yellow |||| |||. How many votes did each colour receive?
Example 2
mediumA survey asked 30 people their favourite season. The results are: Spring 8, Summer 11, Autumn 6, Winter 5. Represent this data using tally marks and verify the total.
Example 3
mediumA student's tally chart for types of vehicles passing the school shows: Cars |||| |||| |||| ||, Buses |||| |, Bicycles ||||, Trucks |||| |||. Convert this to a frequency table and find what fraction of the total vehicles were cars.
Example 4
hardA tally chart records dice rolls. The tallies show: 1 (7 times), 2 (5 times), 3 (9 times), 4 (6 times), 5 (4 times), 6 (9 times). There were supposed to be 42 rolls total. Is the tally chart consistent? If a fair die were rolled 42 times, what would you expect each frequency to be?
Example 5
mediumStudents were asked their favorite color: Red (7), Blue (12), Green (5), Yellow (3). Create the tally marks and find what fraction chose Blue.
