Which of the following is a probability sampling method?

• Judgment sampling

• Convenience sampling

• Simple random sampling

• Quota sampling

In which sampling method does each member of the population have an equal chance of being selected?

• Stratified sampling

• Systematic sampling

• Simple random sampling

• Cluster sampling

Which of the following is a non-probability sampling technique?

• Stratified sampling

• Cluster sampling

• Convenience sampling

• Simple random sampling

What is the primary advantage of using random sampling methods?

• They are easier to implement

• They ensure every individual has an equal chance of selection

• They are less time-consuming

• They are more cost-effective

Which sampling method involves dividing the population into subgroups and selecting samples from each subgroup?

• Stratified sampling

• Systematic sampling

• Cluster sampling

• Convenience sampling

What is the first step in creating a frequency distribution table?

• Determine the class intervals

• Count the frequency of each data point

• Organize the data in ascending order

• Calculate the mean

In a frequency distribution table, what does the 'class width' represent?

• The difference between the highest and lowest data values

• The number of data points in each class interval

• The range of values within each class interval

• The cumulative frequency up to that class interval

Which of the following is NOT typically included in a frequency distribution table?

• Class intervals

• Frequency

• Cumulative frequency

• Mean

What is the purpose of cumulative frequency in a frequency distribution table?

• To show the total number of data points

• To display the running total of frequencies up to each class interval

• To calculate the mean of the data

• To determine the range of the data

How is the 'relative frequency' of a class interval calculated?

• Frequency of the class interval divided by the total number of data points

• Frequency of the class interval multiplied by the total number of data points

• Cumulative frequency divided by the total number of data points

• Cumulative frequency multiplied by the total number of data points
