Study Notes
Data Presentation and Analysis
- The theme is data presentation, and the code is M-G8-WS3.1.
- The subject is mathematics, and the teacher is Ms. Nebras/Mr. Emmanuel.
Frequency Tables and Charts
- A frequency table is a table that shows the frequency of each value in a dataset.
- A bar chart is a graphical representation of a frequency table.
- A pie chart is a circular chart divided into sectors to show the proportion of each category.
Problem-Solving
- To find the least popular method of transport, identify the method with the lowest frequency.
- To find the most popular method of transport, identify the method with the highest frequency.
- To calculate the total number of employees, add up the frequencies of all methods of transport.
Frequency Table and Charts Examples
- Complete a frequency table by counting the number of times each value appears in the dataset.
- Draw a bar chart to show the frequency of each value in the dataset.
- Draw a pie chart to show the proportion of each value in the dataset.
Fractions and Pie Charts
- To find the fraction of counters that are white, divide the number of white counters by the total number of counters.
- To find the fraction of counters that are red, divide the number of red counters by the total number of counters.
- To find the number of black counters, subtract the number of red and white counters from the total number of counters.
Right-Angle Triangles
- To find the missing sides in a right-angle triangle, use the Pythagorean theorem or other trigonometric methods.
Distance and Direction
- To find the distance between two people, use the Pythagorean theorem or other methods to calculate the distance between their positions.
