100 percent sure it's the first one
Answer:
Median: 2 goals
Mean: 2 goals
Step-by-step explanation:
Let's go over the definitions of the terms "median" and "mean",
Median: The number in the middle of the data; the value in the middle of a range of values
Mean: The average number between all values in a range of values
To find the median, let's first look at all the numbers in the data. We're trying to find the median conceded goals, so the numbers are:
0
1
2
3
4
Now, let's find the middle number. Cross off 0 and 4, 1 and 3, and we are left with 2. 2 is the median.
To find the mean, or the average, we must add all of the numbers together, and then divide that number by the amount of terms. There are 5 terms. Let's review them again.
0
1
2
3
4
Add them together to get 10. Then, since there are 5 values, divide by 5. 10/5 = 2. So, the mean is 2.
Answer:
So then the we have perfect linear association. Because the heights and weights of the men are similar.
Step-by-step explanation:
Let X represent the Height and Y the weigth
We have the follwoing dataset:
X: 70, 69
Y: 169, 164
n=2
The correlation coefficient is a "statistical measure that calculates the strength of the relationship between the relative movements of two variables". It's denoted by r and its always between -1 and 1.
And in order to calculate the correlation coefficient we can use this formula:
For our case we have this:
n=2
And if we replace in the formula we got:
So then the we have perfect linear association. Because the heights and weights of the men are similar.
