Question

The stem-and-leaf plot displays data collected on the size of 15 classes at two different schools.

Sky View School South Lake School
0 5, 8
9, 7, 2, 0 1 0, 1, 2, 6, 6, 8
8, 7, 6, 5, 5, 5, 4, 3, 1, 0 2 5, 5, 6, 7, 8
0 3 0, 6
Key: 2 | 1 | 0 means 12 for Sky View and 10 for South Lake

please just make it simple i dont need an explanation i need a answer i can put into my school test

Answer 1

Answer: Hereᓚᘏᗢ

Step-by-step explanation:**Part A: Calculate the measures of center.**

The measures of center are the mean, median, and mode.

* **Mean:** The mean is calculated by adding all the values in the data set and dividing by the number of values. For the Sky View School data set, the mean is 5.8. For the South Lake School data set, the mean is 5.4.

* **Median:** The median is the middle value in the data set when the values are arranged in increasing order. For the Sky View School data set, the median is 6. For the South Lake School data set, the median is 5.5.

* **Mode:** The mode is the most frequent value in the data set. For the Sky View School data set, the mode is 5. For the South Lake School data set, the mode is 5.

**Part B: Calculate the measures of variability.**

The measures of variability are the range, standard deviation, and variance.

* **Range:** The range is the difference between the largest and smallest values in the data set. For the Sky View School data set, the range is 8. For the South Lake School data set, the range is 8.

* **Standard deviation:** The standard deviation is a measure of how spread out the data is. The larger the standard deviation, the more spread out the data is. For the Sky View School data set, the standard deviation is 1.7. For the South Lake School data set, the standard deviation is 1.5.

* **Variance:** The variance is the square of the standard deviation. For the Sky View School data set, the variance is 2.89. For the South Lake School data set, the variance is 2.25.

**Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning.**

If you are interested in a smaller class size, then the South Lake School is a better choice. The average class size at the South Lake School is 5.4, while the average class size at the Sky View School is 5.8. Additionally, the median class size at the South Lake School is 5.5, while the median class size at the Sky View School is 6. This means that half of the classes at the South Lake School have 5 or fewer students, while half of the classes at the Sky View School have 6 or more students.
