i will give brainliest the dot plot shows how many attempts it took for each student to complete a puzzle:
is the median or the mean a better measure of center for these data and why?
mean, because the data are skewed and there are outliers mean, because the data are symmetric and there are no outliers median, because the data are skewed and there are outliers median, because the data are symmetric and there are no outliers

 Mean, because the data are symmetric and there are no outliers.

Step-by-step explanation:

The given dot plot shows how many attempts it took for each student to complete a puzzle.

From the given dot plot, we observe that it has no outlier and the data is symmetric.

Therefore , the mean is a better measure of center for these data because mean the data are symmetric and there are no outliers .

"If a data is skewed or has outliers, then we choose median to measure the center of data over mean."
