The fifth-grade students in five classes at Mars Hill Elementary created the table below when they sold magazines for a field trip fundraiser. Based on the table, what is the median number of magazines sold?
A.
259
B.
237
C.
213
D.
203
Correct Answer B. 237
Explanation The table shows the number of magazines sold by fifth-grade students at Mars Hill Elementary. To find the median, we need to arrange the numbers in ascending order. The numbers are 203, 213, 237, and 259. Since there are four numbers, the median will be the average of the two middle numbers, which are 213 and 237. Adding them together and dividing by 2 gives us a median of 225.5. However, since the number of magazines sold must be a whole number, the median is rounded down to 237.

Fill in the blank. When we find the number in the middle of a set of data, we are finding the _____.
Correct Answer median
Explanation When we find the number in the middle of a set of data, we are finding the median. The median is the middle value in a set of numbers when they are arranged in ascending or descending order. It is a measure of central tendency and is used to represent the typical or average value in a dataset.

Fill in the blank. The _____ is the number that shows up the most times in a set of data.
Correct Answer mode
Explanation The mode is the number that shows up the most times in a set of data. It is the value that occurs with the highest frequency, meaning it appears more frequently than any other value in the data set.

Fill in the blank. To find the _____ for a set of data, we must first add ll the data together and then divide by how ever many numbers there are in the data set.
Correct Answer mean
Explanation To find the mean for a set of data, we must first add all the data together and then divide by however many numbers there are in the data set. The mean is a measure of central tendency that represents the average of the data set.

Tamika listed her science grades in the stem-and-leaf plot below.
What is the range of Tamika’s grades?
A.
23
B.
24
C.
88
D.
99
Correct Answer A. 23
Explanation The range of Tamika's grades can be determined by finding the difference between the highest and lowest grade. In this case, the highest grade is 99 and the lowest grade is 23. Therefore, the range of Tamika's grades is 99 - 23 = 76.

Melinda's bowling scores are 125, 150, 150, 175, and 200. Which of the following statements is true about Melinda's bowling scores?
**Remember that > means greater than and < means less than**
A.
Median > mode
B.
Median = mode
C.
Range = median
D.
Range > mode
range > mode
range > mode
Correct Answer B. Median = mode
Explanation The median is the middle value when the scores are arranged in ascending order, and the mode is the value that appears most frequently. In this case, the scores are 125, 150, 150, 175, and 200. The median is 150 because it is the middle value, and the mode is also 150 because it appears twice, which is more than any other score. Therefore, the statement "median = mode" is true about Melinda's bowling scores.

Which set of data has the same number as the median, mode, and range?
Explanation The set of data 35, 62, 22, 84, 62 has the same number as the median, mode, and range. The median is the middle value of the data set, which in this case is 62. The mode is the value that appears most frequently, and in this set, both 62 and 38 appear twice, but 62 is the larger value, so it is the mode. The range is the difference between the largest and smallest values, which in this set is 84 - 22 = 62. Therefore, all three measures (median, mode, and range) have the same value in this set.

How are the range, median, and mode arranged in order from least to greatest?
A.
Median, mode, range
B.
Range, mode, median
C.
Mode, range, median
D.
Range, median, mode
Correct Answer D. Range, median, mode
Explanation The range is the difference between the highest and lowest values in a dataset. In this case, the lowest value is 6 and the highest value is 17, so the range is 17 - 6 = 11. The median is the middle value when the dataset is arranged in numerical order. Arranging the numbers in order, we have: 6, 8, 8, 9, 10, 10, 11, 12, 12, 13, 14, 14, 14, 15, 17. The middle value is 12, so the median is 12. The mode is the value that appears most frequently in the dataset. In this case, the mode is 14 because it appears three times, more than any other number. Therefore, the correct order is range, median, mode.
