To determine the best measure of central tendency for the given data, we need to consider the nature of the data and the presence of the undetermined score. Here are the steps to identify the most appropriate measure:

1. **Identify the measures of central tendency**: The common measures of central tendency are the mean, median, and mode.

2. **Consider the mean**: The mean is the arithmetic average of all the scores. However, since one score is undetermined, calculating the mean is not possible because it requires all data points to be known.

3. **Consider the median**: The median is the middle value when the scores are arranged in ascending or descending order. The median is less affected by the undetermined score because it only depends on the order of the data, not the actual values of all data points.

4. **Consider the mode**: The mode is the most frequently occurring score in the data set. While the mode can be determined without knowing all the scores, it may not provide a useful summary if the data set does not have a clear mode or if the mode is not representative of the central tendency.

5. **Evaluate the situation**: Given that one score is undetermined, the mean cannot be calculated accurately. The mode may not be representative or useful in this context. The median, on the other hand, can still be determined and provides a measure of central tendency that is not affected by the undetermined score.

Therefore, the best measure of central tendency for these data is the median.

A researcher is measuring the amount of time needed to solve a set of anagrams for a sample of n = 15 students. However, one of the participants fails to solve the problems so the researcher has an undetermined score. What is the best measure of central tendency for these data?
