Answer:
Explanation:
The average speed is a measure of the typical or central speed of an object or group of objects over a certain distance or time period. There are three commonly used measures of center to describe average speeds: mean, median, and mode.
1.Mean: The mean speed is calculated by adding up all the speeds and dividing by the total number of speeds. It represents the average speed across all observations. The mean speed can be affected by outliers, or extreme values that are far from the other observations.
2.Median: The median speed is the middle value when all the speeds are arranged in order. It represents the speed that separates the faster half of the observations from the slower half. The median speed is less affected by outliers than the mean speed.
3.Mode: The mode speed is the most frequent speed in the dataset. It represents the speed that occurs most often. If there are multiple modes, the dataset is considered to be multimodal. The mode speed is useful for identifying common speeds, but it does not necessarily represent the typical or central speed of the dataset.
Overall, each measure of center has its own strengths and weaknesses for describing average speeds. The mean speed is useful for summarizing the overall average, but it can be affected by outliers. The median speed is useful for identifying the middle value of the dataset and is less affected by outliers. The mode speed is useful for identifying common speeds but does not necessarily represent the typical or central speed of the dataset.
