Solution by Steps
step 1
To describe the shape of the distribution, we look at the dot plot and observe where the data points are concentrated
step 2
The data points are concentrated around the 12 and 13-centimeter marks, indicating a central clustering
step 3
To find the center of the distribution, we calculate the median of the lengths
step 4
The median is the middle value when the data points are ordered from least to greatest
step 5
According to the asksia-ll calculator, the median of the given data set is centimeters
step 6
To determine the spread of the distribution, we calculate the range of the lengths
step 7
The range is the difference between the maximum and minimum values in the data set
step 8
According to the asksia-ll calculator, the range of the given data set is centimeters
[question 1] Answer
Shape: The distribution of lengths is centrally clustered around 12 and 13 centimeters.
Center: The median of the lengths is centimeters.
Spread: The range of the lengths is centimeters.
Key Concept
Describing a distribution involves discussing its shape, center, and spread.
Explanation
The shape is observed from the concentration of data points, the center is determined by the median, and the spread is calculated as the range of the data set.
