Final answer:
The mean, median, and mode are all different measures of central tendency that can describe the prices of the couches. The median value of $500 best describes the prices of the couches as it is not influenced by extreme values and represents the typical price.
Step-by-step explanation:
The mean, median, and mode are all different measures of central tendency that can describe the prices of the couches.
The mean is found by adding up all the prices and dividing by the number of couches. In this case, the mean is $755. The mean can be influenced by extreme values, so it may not accurately represent the typical price of a couch.
The median is the middle value when the data is arranged in order. In this case, the median is $500. The median is not affected by extreme values, so it can be a good measure of the typical price.
The mode is the value that appears most frequently. In this case, there are two modes: $450 and $575. The mode can be useful in showing common prices, but it may not capture the full range of prices.
Based on these measures, the median value of $500 best describes the prices of the couches as it is not influenced by extreme values and represents the typical price.
