Match the following statistical terms with their definitions:
Mean = Average of a set of numbers Median = Middle value of a data set when arranged in ascending order Standard Deviation = Measure of the amount of variation or dispersion of a set of values Hypothesis Testing = Statistical method used to make inferences about a population parameter
Match the following statistical distributions with their characteristics:
Normal Distribution = Symmetric bell-shaped curve with mean, median, and mode all equal Binomial Distribution = Describes the number of successes in a fixed number of independent trials Poisson Distribution = Models the number of events occurring in a fixed interval of time or space Exponential Distribution = Describes the time between events in a Poisson process
Match the following sampling techniques with their descriptions:
Simple Random Sampling = Every member of the population has an equal chance of being selected Stratified Sampling = Divides the population into subgroups and then samples from each subgroup Systematic Sampling = Selects every kth element from a list of population members Cluster Sampling = Divides the population into clusters and then randomly selects some of the clusters to be included in the sample
Match the following statistical tests with their primary applications:
t-test = Comparing means of two groups ANOVA = Comparing means of three or more groups Chi-square test = Testing independence of categorical variables Correlation analysis = Measuring strength of association between variables
Match the following research designs with their characteristics:
Experimental design = Controlled manipulation of variables Quasi-experimental design = Lacks random assignment to groups Survey design = Collecting data from a sample to make inferences about a population Longitudinal design = Observing the same subjects repeatedly over a period of time
Match the following measures of central tendency with their definitions:
Mean = Average of a set of values Median = Middle value in a data set when arranged in ascending order Mode = Most frequently occurring value in a data set Geometric mean = Nth root of the product of n values
