Find the mean and median for the following set of data. 16,13,11,12,16,23,18?

To find the mean, add up all the numbers and divide by the total number of values:

Mean = (16 + 13 + 11 + 12 + 16 + 23 + 18) / 7
Mean = 109 / 7
Mean = 15.57

To find the median, first arrange the numbers in ascending order:

11, 12, 13, 16, 16, 18, 23

Since there are 7 numbers, the median will be the middle number when arranged in ascending order. In this case, the median is 16.

1. Mean = 15

Mean is the sum of all values divided by the number of values in a dataset. In this case, the mean can be calculated as
(16 + 13 + 11 + 12 + 16 + 23 + 18) / 7 = 105 / 7 = 15
Therefore, the mean of the given dataset is 15.

2. Median = 15

Median is the middle value of a dataset when assorted in numerical order. In this case, we can assort the data as
{11,12,13,16,16,18,23}
Since there are odd number of values in the dataset, the middle value is the median. Therefore, the median of the given dataset is 15.
