Final answer:
To calculate the mean absolute deviation (MAD) for data in a pictograph, count and convert the pictograph images to numerical data, calculate the mean, find the absolute deviation for each data point, and then find the average of those absolute deviations.
Step-by-step explanation:
To find the mean absolute deviation (MAD) of the data represented in a pictograph where one sundae picture equals two sundaes, you would follow these steps:
- Count the total number of sundae pictures in the pictograph.
- Multiply the number of pictures by two to get the total number of sundaes since one picture equals two sundaes.
- Calculate the mean (average) number of sundaes by dividing the total number of sundaes by the number of data points.
- Find the absolute deviation of each data point by subtracting the mean from each value and taking the absolute value of the result.
- Finally, calculate the MAD by finding the mean of these absolute deviations.
It is important to note that without the actual data from the pictograph, we cannot calculate a specific MAD. However, the steps provided will guide you in calculating it once you have the necessary data.
