This sample is likely biased because it only includes people who are attending a football game, who are more likely to have a higher interest in football compared to the general population.
determine whether each sample is a random sample or a biased sample all 2nd period students were asked where they want to go to college
This sample is likely biased because it only includes students in the 2nd period class, who may not be representative of the entire student population in terms of college aspirations.
find the mode of the set of numbers 63,79,44,90,79
The mode is the number that appears most frequently in a set of numbers. In this set, the number 79 appears twice, which is more than any other number. Therefore, the mode of the set of numbers 63, 79, 44, 90, 79 is 79.
find the median of the set of numbers 16,26,18,23,10,19,28
To find the median of a set of numbers, they must first be arranged in numerical order.

The numbers 10, 16, 18, 19, 23, 26, 28 arranged in ascending order.

Since there are 7 numbers in the set, the median will be the middle number when the numbers are ordered.

The middle number is 19, so the median of the set of numbers 16, 26, 18, 23, 10, 19, 28 is 19.
calculate the mean for 65, 65, 81, 75, 90, 95
To calculate the mean, you add up all the numbers and then divide by how many numbers there are.

Adding all the numbers together:
65 + 65 + 81 + 75 + 90 + 95 = 471

Now, there are 6 numbers in the set.

Divide the sum by the number of numbers:
471 รท 6 = 78.5

Therefore, the mean of the numbers 65, 65, 81, 75, 90, 95 is 78.5.
