- For problem 1a, the completed frequency table is:
- Black: Tally = ||||, Frequency = 5
- Red: Tally = |||| |||| |, Frequency = 9
- White: Tally = ||||, Frequency = 4
- Silver: Tally = ||, Frequency = 2
- For problem 1b, to draw the bar chart:
- Label the horizontal axis with the car colors: Black, Red, White, Silver.
- Label the vertical axis from 0 to at least 9 (the highest frequency) with a suitable scale (e.g., 1 unit per grid line).
- Draw bars for each color with heights corresponding to their frequencies: Black = 5 units, Red = 9 units, White = 4 units, Silver = 2 units.
- For problem 2a, the completed grouped frequency table is:
- 1.40 - 1.49: Tally = |, Frequency = 1
- 1.50 - 1.59: Tally = |||| |, Frequency = 6
- 1.60 - 1.69: Tally = |||| |||, Frequency = 8
- 1.70 - 1.79: Tally = ||||, Frequency = 4
- 1.80 - 1.89: Tally = |, Frequency = 1
- 1.90 - 1.99: Tally = |, Frequency = 1
- For problem 2b, to draw the bar chart:
- Label the horizontal axis with the height intervals: 1.40-1.49, 1.50-1.59, 1.60-1.69, 1.70-1.79, 1.80-1.89, 1.90-1.99.
- Label the vertical axis from 0 to at least 8 (the highest frequency) with a suitable scale (e.g., 1 unit per grid line).
- Draw bars for each interval with heights corresponding to their frequencies: 1.40-1.49 = 1 unit, 1.50-1.59 = 6 units, 1.60-1.69 = 8 units, 1.70-1.79 = 4 units, 1.80-1.89 = 1 unit, 1.90-1.99 = 1 unit.
Parent Tip: Review the logic above to help your child master the concept of frequency tables worksheet.
