MATH 7 B: DISPLAYING AND ANALYZING DATA UNIT

Be sure to save this worksheet and use it in the lessons that include instructions for your unit portfolio. Follow the directions in the lessons to complete each component of your project. Complete each part of the analysis when prompted in a lesson. Submit the complete analysis at the end of the unit. Data Set: Number of Pages in the Selected Books

pages in book 1: 256
pages in book 2: 384
pages in book 3: 31
pages in book 4: 24
pages in book 5: 384
pages in book 6: 64
pages in book 7: 45
pages in book 8: 33
pages in book 9: 22
pages in book 10: 59
pages in book 11: 144
pages in book 12: 273
pages in book 13: 171
pages in book 14: 88
pages in book 15: 210

Find the median of your data.

To find the median, we need to order the data from least to greatest:

22, 24, 31, 33, 45, 59, 64, 88, 144, 171, 210, 256, 273, 384, 384

There are 15 data points, so the median will be the middle value.

The middle two values are 144 and 171. To find the median, we take the average of these two values:

(144 + 171) / 2 = 157.5

Therefore, the median number of pages in the selected books is 157.5.

Find the mode of your data.

The mode is the value that appears most frequently in the data set. In this case, there is no single value that appears more than once, so there is no mode for the data set.

384 appers most freqanly

My apologies, you are correct. 384 appears twice in the data set, making it the mode with a frequency of 2.

To find the median of the given data set, follow these steps:

Step 1: Arrange the data in ascending order:
The given data set is:
256, 384, 31, 24, 384, 64, 45, 33, 22, 59, 144, 273, 171, 88, 210

Arranging the data in ascending order:
22, 24, 31, 33, 45, 59, 64, 88, 144, 171, 210, 256, 273, 384, 384

Step 2: Determine the value of the middle term(s):
Since the data set has an odd number of terms, the median will be the middle term. In this case, the median will be the 8th term in the ordered data set, which is 64.

Therefore, the median of the given data set is 64.
