To analyze the given data set
, we will calculate the mean (
), median (
), and mode (
). We will also draw a graph.1. **Mean (
)**:
2. **Median (
)**: To find the median, first arrange the data in ascending order:
Since there are 10 numbers (an even number), the median is the average of the 5th and 6th values:
3. **Mode (
)**: The mode is the number that appears most frequently. In this data set, 50 appears three times, which is more than any other number.
4. **Graph**: A simple way to visualize this data is with a histogram or a bar chart. Here's how you can represent it: - On the x-axis, list the unique data points: 20, 30, 40, 50, 60, 70, 80. - On the y-axis, indicate the frequency of each data point. - Draw bars for each data point with heights corresponding to their frequencies: - 20: 1 - 30: 1 - 40: 1 - 50: 3 - 60: 1 - 70: 2 - 80: 1This graph will help visualize the distribution of the data set.
