The mean is the average of the dataset. To calculate the mean, add up all the numbers in the dataset and divide by the total number of values.
Mean = (10 + 11 + 12 + 13) / 4 = 46 / 4 = 11.5
The median is the middle value of the dataset when arranged in ascending order. Since there are an even number of values in the dataset, the median is the average of the two middle values.
Median = (11 + 12) / 2 = 23 / 2 = 11.5
The spread can be measured in different ways, but one common measure of spread is the range, which is the difference between the highest and lowest values in the dataset.
Spread = 13 - 10 = 3
Therefore, the values of the mean, median, and spread for the dataset are:
- Mean: 11.5
- Median: 11.5
- Spread: 3
What are the values of the mean, median, and spread for the dataset shown in the bar graph? 10 11 12 13 the mean the median the spread
