Final Answer:
To increase the mean of a set of sample values, add a value that is higher than the current mean of the samples.
Step-by-step explanation:
The mean of a set of sample values is calculated by summing all the values and then dividing by the total number of samples. To increase the mean, you need to add a value that is greater than the current mean. This is because the mean is sensitive to the magnitude of the individual values. By introducing a higher value, you effectively pull the mean towards that higher value.
For example, let's consider a set of sample values: 2, 4, 6, and 8, with a mean of 5. If you add a value greater than 5, such as 10, the new mean will be higher than the original mean. The new mean is calculated by summing 2 + 4 + 6 + 8 + 10 and dividing by 5, resulting in a mean of 6.
It's essential to note that the impact of adding a single value on the mean is influenced by the magnitude of that value relative to the existing values. Adding an extremely high value can significantly raise the mean, while a smaller value might have a more moderate effect.
