To estimate the median from a bar graph (or histogram), you typically need to identify the total number of observations (sum of frequencies) and find the median class where the cumulative frequency reaches the halfway point.
Since I don't have access to the image you mentioned, I will describe how you might find the median based on the construction of the graph.
- Calculate Total Frequency: Add all the frequencies represented by the bars.
- Find the Halfway Point: Divide the total frequency by 2 to determine the point at which the median lies.
- Cumulative Frequency: Starting from the first bin, add the frequencies cumulatively until you reach or exceed the halfway point. The bin where this occurs is the median bin.
Given those steps, without seeing the graph, I cannot determine the median directly. However, you should follow this process with the data from your bar graph to find which bin contains the median.
If you can provide the actual frequencies for each bin or describe the graph in detail, I can help you determine the median.
