Why is it sometimes easier to use a frequency table to interpret data than to examine the distribution of raw scores?

Frequency tables display patterns, organizing the data by how often each score occurs.

A frequency table transforms the raw scores by showing the means.

Raw scores are not based on the sample.

Raw scores do not represent the data.

A normal distribution is:

bell-shaped, symmetric, and unimodal.

In comparing frequency tables with grouped frequency tables for the same set of data, which of the following would be true?

If the data set is large the grouped frequency table would be easier to decipher.

Depending on the width of class intervals it is possible that some scores may not be counted in a grouped frequency table.

Because of overlapping class intervals, the total frequency for a grouped frequency table would exceed that of a frequency table.

It is generally harder to spot patterns in the data when using a grouped frequency table.

Imagine a researcher found that 65% of bystanders helped a female who dropped her packages but only 32% helped a male that dropped his packages. What type of graph would be appropriate to display this data?

not enough information is available to answer the question

Professor Arenas recently administered a statistics exam and was surprised to see that the distribution of scores was negatively skewed. What would a negatively skewed distribution indicate for this example?

That most students did well on the exam but a few did very poorly.

That students were at the extreme; some did very well and others did very poorly.

That most students did poorly on the exam but a few did very well.

That there was very little variation in his class; everyone scored about the same.

If students in a college math class are given an exam intended for middle school math students it would probably result in:

a positively skewed distribution.
