How does the mode differ from the median?
✔✔The mode is the value that appears most frequently in a dataset, while the median is the
middle value when the data is arranged in order, making them useful for different types of data.
What does the range of a dataset tell you?
✔✔The range indicates the difference between the highest and lowest values in a dataset,
providing a simple measure of the dataset's spread.
How can outliers affect the mean and median of a dataset?
✔✔Outliers can significantly skew the mean, pulling it towards the extreme value, while the
median remains relatively unaffected, providing a more robust measure of central tendency.
How do you interpret a positive correlation coefficient?
✔✔A positive correlation coefficient, ranging from 0 to +1, indicates a direct relationship
between two variables, meaning that as one variable increases, the other tends to increase as
well.

, What is a scatter plot, and how is it useful in statistics?
✔✔A scatter plot visually represents the relationship between two quantitative variables,
allowing for easy identification of correlations, trends, and outliers within the data.
What role does sampling error play in research?
✔✔Sampling error is the difference between the sample statistic and the actual population
parameter, highlighting the potential inaccuracies that can arise from using a sample rather than
the entire population.
What is the purpose of creating a frequency distribution?
✔✔A frequency distribution organizes data into categories or intervals, showing how often each
value or range occurs, which helps in understanding the distribution and patterns within the data.
How can you identify a bimodal distribution?
✔✔A bimodal distribution has two distinct modes or peaks, indicating the presence of two
prevalent groups within the dataset, which can suggest differing characteristics among the data
points.
