What does it mean when a frequency table is incomplete?

• It shows all the data and counts accurately.

• It does not show all the data or counts for certain ranges, making it difficult to understand the full data set.

• It includes extra data that is not relevant to the analysis.

• It is perfectly organized and easy to interpret.

How do you measure length using a ruler?

• Align the object with the zero mark on the ruler and read the measurement at the other end of the object.

• Place the ruler on the object and measure from the middle to the end.

• Use the ruler to draw a line equal to the length of the object.

• Estimate the length by comparing it to the length of the ruler.

How do you create a frequency table?

• By counting how many times each value appears in a data set and listing the values with their corresponding counts.

• By averaging the values in a data set and presenting them in a table format.

• By sorting the values in ascending order and displaying them in a list.

• By selecting random values from the data set and creating a table with those values.

What is a data set?

• A data set is a collection of related values or observations, often used for analysis.

• A data set is a single value used for comparison.

• A data set is a random assortment of numbers without any relation.

• A data set is a graphical representation of data points.

What is a frequency distribution?

• A method to calculate the mean of a data set.

• A frequency distribution shows how often each value occurs in a data set, often represented in a table or graph.

• A graphical representation of the relationship between two variables.

• A technique used to find the median of a data set.

How do you interpret a dot plot?

• Count the number of dots above each value to see how many times that value occurs.

• Look for the highest dot to determine the mode.

• Add all the dots together to find the total number of values.

• Ignore the dots and focus on the labels.
