Question
A student records their reaction time in milliseconds for a series of tests. If the average reaction time is 250 ms, represent this data graphically and explain what the graph indicates about the student's reaction time.
Answer
The data can be represented as a bar graph with the x-axis showing the test number and the y-axis showing reaction time in milliseconds. The graph indicates that the student's average reaction time is consistent across tests, suggesting they have a stable response time.
Explanation
This answer is strong because it clearly describes how to translate numerical data into a graphical format and interprets the implications of the data. The question tests the student's ability to visualize and analyze reaction time data.
Common mistake
Misinterpreting Data Formats
Students often confuse numerical data with graphical representations, leading to incorrect translations between the two forms.
Practice converting data from one format to another by using clear examples and ensuring understanding of how to read graphs and tables accurately.
