sample mean\t○\t○
sample standard deviation\t○\t○
population standard deviation\t○\t○
population mean\t○\t○

Explanation:

Step1: Recall definitions

A parameter is a characteristic of a population, while a statistic is a characteristic of a sample.

Step2: Classify sample - related measures

Sample mean and sample standard deviation are calculated from sample data, so they are statistics.

Step3: Classify population - related measures

Population standard deviation and population mean are characteristics of the entire population, so they are parameters.

Answer:

Sample mean: Statistic
Sample standard deviation: Statistic
Population standard deviation: Parameter
Population mean: Parameter
