A researcher measures the eye movements of 100 participants as they read ambiguous words embedded within sentences. Because eye movements are measured in milliseconds, and there are likely to be many different times measured, the researcher decides to use a __________ to help make sense of these data.
A)frequency polygraph
B)scatterplot
C)grouped frequency table
D)horizontal bar chart

A grouped frequency table would be the best choice for organizing and summarizing data with many different time measurements. It allows the researcher to group the data into intervals and easily see the frequency of measurements that fall within each interval. This can provide a clearer picture of the distribution of eye movements across the sample of participants. The other options would not be as useful for this type of data. A frequency polygraph and horizontal bar chart are not commonly used for summarizing continuous data like eye movement measurements. A scatterplot is used to show the relationship between two variables, which may not be relevant in this case where the focus is on a single variable.
