How do measures of central tendency help in statistics?
✔✔Measures of central tendency, like the mean, median, and mode, provide a single value that
represents the center of a dataset, helping to understand its general trend.
What is the difference between the mean and median?
✔✔The mean is the average of all data points, while the median is the middle value when the
data is ordered, providing a better measure of central tendency for skewed distributions.
What does variability in a dataset indicate?
✔✔Variability shows how spread out the data points are, indicating the degree of diversity or
consistency within the dataset.
How is the range calculated in statistics?
✔✔The range is calculated by subtracting the smallest value in a dataset from the largest value,
providing a measure of the spread.

, What are quartiles, and why are they useful?
✔✔Quartiles divide a dataset into four equal parts, helping to understand the distribution and
identify outliers by showing where the bulk of the data lies.
What is the purpose of a frequency distribution?
✔✔A frequency distribution organizes data into classes or intervals, showing how many
observations fall within each range, making it easier to visualize data patterns.
What is a histogram, and what does it represent?
✔✔A histogram is a graphical representation of a frequency distribution, displaying the number
of observations within each interval as bars.
How do you interpret a box plot?
✔✔A box plot visually summarizes data by showing the median, quartiles, and potential outliers,
providing insights into the distribution's spread and symmetry.
What is the significance of the standard deviation?
