Answer :
Final answer:
The mean (average) of the data set is 157.5, the median (middle number), Measures of Central Tendency is 160, the mode (most frequent number) is 145, and the midrange (average of smallest and largest number) is 165.
Explanation:
The subject of this question is statistics, particularly calculating and understanding the key measures of central tendency in a data set: the mean, median, and mode. The mean is the average, which is calculated by adding all the numbers together and then dividing by the number of numbers. For this data set, the mean is 157.5.The median is the middle number when the data is arranged in numerical order from least to greatest. When the data set has an even number of observations, the median is the average of the two middle numbers. In this case, the median is 160. The mode is the number that appears most frequently, which is 145 in this data set. Finally, the midrange is the average of the smallest and largest number in the set, and for this data set, the midrange is 165.
