2: 0111 (2|0 = 20 grams
1. Describe the shape, center and spread of the data in content.
2.Describe How to find the range number of grams of these cereals. Range _______
3. Do you think the mean amount of salt to be great than, less than or about equal to the median? _________ Explain.
4. Draw a histogram of the given Data values (hint use grams on the x-axis and Frequency on the y-axis)
Use the Vocabulary words below to match the description provided.
Mean, Median, Mode, Q1, Q2, Standard Deviation, Range, IQR
_________Compares the extremes of the data
__________Where the peaks of a histogram are
__________The center of the lower half of the data
__________The "balancing point" of the data
__________Summarizes the spread of the central 50% of the data
__________Splits a histogram in halves
__________ A good choice for decribing the center of skewed data
__________Summarizes how far each data value is from the average of the data
