Which of the following is a single value from within a data series? 1. Data point 2. Tick mark 3. Trendline 4. Gridline

The correct answer to the question is:

Final Answer

1. Data point

A data point is a single value that represents a particular observation within a data series. In the context of data visualization, such as graphs or charts, each data point corresponds to a value on the x-axis and y-axis, indicating precise coordinates in a plotted dataset.

• Tick mark: This is a line or mark on an axis of a chart that indicates specific intervals or values but does not represent data itself.
• Trendline: This is a line that depicts the general direction of data points in a scatter plot but is not a single data value.
• Gridline: These are the lines that extend across the graph to help guide the viewer’s eye and provide context but do not represent actual data points.

Thus, when considering the terminology used in data analysis and visualization, it is clear that data points are crucial as they are the individual numeric values we analyze.
