statistics?
What is the purpose of statistical notation? To provide a standardized way to represent statistical concepts and calculations.
What is a frequency distribution? A summary of how often each value occurs in a dataset.
What is a grouped frequency distribution table? A table that displays the frequency of data points grouped into intervals.
What is the mean in statistics? The average value of a dataset, calculated by summing all values and dividing by
the number of values.
What is variability in statistics? A measure of how spread out the values in a dataset are.
What is a z-score? A statistical measurement that describes a value's relationship to the mean of a
group of values.
What is the purpose of hypothesis testing? To determine whether there is enough evidence to reject a null hypothesis.
What is the t statistic used for? To determine if there is a significant difference between the means of two groups.
What is the difference between independent and related Independent samples are from different groups, while related samples are from the
samples in t-tests? same group measured at different times.
What does ANOVA stand for? Analysis of Variance.
, What is the purpose of correlation in statistics? To measure the strength and direction of the relationship between two variables.

What is the importance of problem-solving in statistics? To apply statistical methods to real-world issues and derive meaningful conclusions.
What is the significance of the null hypothesis? It is a statement that there is no effect or no difference, serving as a baseline for
testing.
What does it mean to reject the null hypothesis? It indicates that there is sufficient evidence to support an alternative hypothesis.
