1. What is the mean of the following dataset: 5, 10, 15, 20, 25?
   1. 15
   2. 10
   3. 20
   4. 25
2. Which measure of central tendency is the middle value in an ordered dataset?
   1. Mean
   2. Median
   3. Mode
   4. Range
3. How do you calculate the mode of a dataset?
   1. By finding the average of all data points
   2. By identifying the middle value in an ordered dataset
   3. By finding the most frequently occurring value(s)
   4. By subtracting the minimum value from the maximum value
4. If a dataset has the values 3, 7, 7, 2, and 5, what is the mode?
   1. 2
   2. 5
   3. 7
   4. There is no mode
5. Which measure of central tendency is most affected by outliers?
   1. Mean
   2. Median
   3. Mode
   4. Range
6. What is the median of the dataset 45, 50, 55, 60, 65?
   1. 50
   2. 55
   3. 60
   4. 65
7. In a dataset with an even number of values, how is the median calculated?
   1. By averaging the two middle values
   2. By finding the most frequent value
   3. By summing all values and dividing by the number of data points
   4. By subtracting the minimum value from the maximum value
8. If the dataset is 12, 15, 22, 22, and 24, what is the mode?
   1. 15
   2. 22
   3. 12
   4. 24
9. What is the purpose of calculating the mean of a dataset?
   1. To find the most common value
   2. To identify the middle value
   3. To summarize the central value of the dataset
   4. To determine the spread of the dataset
10. When is it more appropriate to use the median instead of the mean as a measure of central tendency?
    1. When the dataset has no mode
    2. When the dataset is skewed or has outliers
    3. When the dataset has an even number of values
    4. When the dataset has a uniform distribution
