Question
What are the mean and median of the following dataset?
5, 7, 11, 11, 6
(1 point)
Mean of the dataset =
.
Median of the dataset =
.
To find the mean of the dataset, you need to add up all the numbers and then divide the sum by the total number of values.
Mean of the dataset = (5 + 7 + 11 + 11 + 6) / 5 = 8
To find the median of the dataset, you need to arrange the numbers in ascending order and then find the middle value. If there is an even number of values, find the average of the two middle values.
Arranged dataset: 5, 6, 7, 11, 11
Median of the dataset = 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?(1 point)
To find the spread of a dataset, you need to calculate the range, which is the difference between the maximum value and the minimum value.
Dataset: 0, 6, 7, 0, 1, 1, 2, 0, 3, 1
Maximum value: 7
Minimum value: 0
Spread = Maximum value - Minimum value = 7 - 0 = 7
To find the mean (average) and median of a dataset, follow these steps:
Step 1: Arrange the dataset in ascending order:
5, 6, 7, 11, 11
Step 2: Calculate the mean:
Mean = (sum of all the numbers in the dataset) / (total number of data points)
Mean = (5 + 6 + 7 + 11 + 11) / 5
Mean = 40 / 5
Mean = 8
Step 3: Calculate the median:
Median is the middle value of the dataset when arranged in ascending order.
Since there are 5 data points, the middle value is the 3rd value, which is 7.
Mean of the dataset = 8
Median of the dataset = 7
