The mean is always the best measure of central tendency, regardless of the dataset's distribution. The median is more resistant to outliers compared to the mean. The mode can only be used for numerical data, not categorical data. In a symmetric dataset, the mean, median, and mode are usually equal. For grouped data, the formula to compute the mean involves summing the products of frequencies and midpoints. The median divides a dataset into three equal parts. A dataset can have more than one mode. In ungrouped data, the median is always the value at the exact center of the dataset. The mode is the most frequently occurring value in a dataset.
Understand the Problem
The question involves evaluating multiple statistical statements about mean, median, and mode, determining if each statement is true or false based on statistical principles.
Answer
1: FALSE, 2: TRUE, 3: FALSE, 4: TRUE, 5: TRUE, 6: FALSE, 7: TRUE, 8: TRUE, 9: TRUE

More Information
The mean isn't always best when data is skewed. The median is better for outlier resistance, and the mode is useful for both numerical and categorical data.
Tips
A common mistake is believing the mean is always the best measure. It's sensitive to outliers.
