Final answer:
Speaker labels and time-stamps in transcripts should be given with precise start and stop times, while axes on a graph should be labeled with variable names and units, and be scaled appropriately for the data represented.
Step-by-step explanation:
Speaker labels and marks with time-stamps should be clearly indicated for referencing specific parts of an audio or video recording in a transcript. For instance, you would give the start and stop times for the segment you are transcribing. These should be shown on the player in hours (if available), minutes, and seconds, such as 00:12:34-00:15:27 indicating the segment begins at 12 minutes and 34 seconds and ends at 15 minutes and 27 seconds.
When labeling the axes of a graph, you should label each axis with the name of the variable it represents, along with the symbol for its units in parentheses, if applicable. For the x-axis, an example would be Time (min). It is important to also determine the best scale for the graph to ensure all data can be accurately represented and easily read. If time is measured every 10 minutes, then numbering the x-axis from 0 to 70 minutes with a tick mark every 10 minutes might be appropriate. Similarly, if measuring distance, the y-axis might range from 0 km to 160 km, with tick marks every 10 km for clarity and ease of interpretation.
