What are the mean and median of the following dataset?
5, 7, 11, 11, 6
(1 point)
The mean is (5+7+11+11+6)/5 = 8
To find the median, we first need to put the numbers in order:
5, 6, 7, 11, 11
There are two middle numbers, 7 and 11, so we take the average of these two:
median = (7+11)/2 = 9
thats not the correct median
I apologize for my mistake earlier. Since we have an odd number of elements in the dataset (5), the median can be found by sorting the elements in ascending order and choosing the middle element. Therefore, the median of the dataset: 5, 7, 11, 11, 6 is 7.
Lori asks some of her friends how many pets they have. The answers are as follows: 0, 6, 7, 0, 1, 1, 2, 0, 3, 1. What is the spread of this dataset?
To find the spread of a dataset, we need to look at the range and interquartile range (IQR).
- Range: The range is the difference between the largest and smallest values in the dataset. In this case, the largest value is 7 and the smallest is 0, so the range is 7 - 0 = 7.
- Interquartile range (IQR): The IQR is a measure of how spread out the middle half of the data is. To find it, we first need to find the quartiles. The median of the dataset is (0, 0, 1, 1, 1, 2, 3, 6, 7) is 1 (the middle value).
We can split the dataset into two parts at the median value. This gives us (0, 0, 1, 1) for the lower half, and (2, 3, 6, 7) for the upper half. The median of the lower half is 0.5 (the average of the two middle values) and the median of the upper half is 4.5 (again, the average of the two middle values).
The IQR is the difference between the upper and lower quartiles. Therefore, IQR = 4.5 - 0.5 = 4.
So, the spread of the dataset is represented by a range of 7 and an IQR of 4.
Median of the dataset?
bot what is the Median of the dataset?
bot?
bot anwser me
To find the mean and median of a dataset, follow these steps:
Mean:
1. Add up all the numbers in the dataset: 5 + 7 + 11 + 11 + 6 = 40.
2. Divide the sum by the total number of values in the dataset: 40 / 5 = 8.
3. Therefore, the mean of the dataset is 8.
Median:
1. Arrange the numbers in ascending order: 5, 6, 7, 11, 11.
2. Since the dataset has an odd number of values, the median is the middle value.
3. In this case, the middle value is 7.
4. Therefore, the median of the dataset is 7.
So, the mean of the dataset is 8 and the median is 7.
