How to calculate average hours worked from bar graph

Answer: To calculate the average hours worked from a bar graph, you need to follow these steps:

  1. Determine the number of data points: Look at the bar graph and count the number of bars or data points representing different categories or individuals.

  2. Identify the hours worked: Each bar on the graph represents a specific value, which in this case is the number of hours worked. Take note of the height or length of each bar, as it indicates the corresponding number of hours worked.

  3. Sum the hours worked: Add up the values of all the bars on the graph to get the total number of hours worked.

  4. Calculate the average: Divide the total number of hours worked by the number of data points. This will give you the average hours worked.

Formula:

Average = Sum of hours worked / Number of data points

For example, let’s say you have a bar graph representing the hours worked by five individuals:

Individual A: 40 hours
Individual B: 35 hours
Individual C: 45 hours
Individual D: 30 hours
Individual E: 50 hours

Sum of hours worked = 40 + 35 + 45 + 30 + 50 = 200 hours
Number of data points = 5

Average hours worked = 200 / 5 = 40 hours

Therefore, the average hours worked, based on the bar graph, is 40 hours.

Here’s the Python code to calculate the average hours worked based on a bar graph:

def calculate_average_hours(bar_values):
    total_hours = sum(bar_values)
    num_data_points = len(bar_values)
    average_hours = total_hours / num_data_points
    return average_hours

# Example bar values representing hours worked
bar_values = [40, 35, 45, 30, 50]

average = calculate_average_hours(bar_values)
print("Average hours worked:", average, "hours")

In the code above, we define a function called calculate_average_hours that takes in a list of bar values representing hours worked. It calculates the total number of hours by summing up the bar values, determines the number of data points by getting the length of the list, and then divides the total hours by the number of data points to obtain the average hours. Finally, it prints out the average hours worked.

You can customize the bar_values list with your own data to calculate the average hours worked based on your specific bar graph.
