Comparing Prices of Skateboards: A Statistical Analysis

In today's digital age, online shopping has become a norm, and consumers are constantly looking for the best deals on their desired products. Nikko, a skateboard enthusiast, has collected data on the prices of skateboards from seven different online stores. In this article, we will analyze the data and compare the prices of skateboards at these online stores.

The data collected by Nikko is shown in the table below:

Price
$67.50
$70.00
$62.25
$65.25
$58.75
$62.00
$68.20

To understand the data better, we need to calculate some descriptive statistics. The mean, median, mode, and range of the data are calculated as follows:

Mean: The mean is calculated by summing up all the values and dividing by the number of values. In this case, the mean is calculated as follows:
$\begin{aligned} \text{Mean} &= \frac{\$67.50 + \$70.00 + \$62.25 + \$65.25 + \$58.75 + \$62.00 + \$68.20}{7} \\ &= \frac{\$395.75}{7} \\ &= \$56.43 \end{aligned}$
Median: The median is the middle value of the data when it is arranged in ascending order. In this case, the median is $62.25.
Mode: The mode is the value that appears most frequently in the data. In this case, there is no mode since each value appears only once.
Range: The range is the difference between the highest and lowest values in the data. In this case, the range is calculated as follows:
$\begin{aligned} \text{Range} &= \$70.00 - \$58.75 \\ &= \$11.25 \end{aligned}$

Now that we have calculated the descriptive statistics, let's compare the prices of skateboards at the seven online stores.

Cheapest Store: The cheapest store is the one that offers the lowest price. In this case, the cheapest store is the one that offers a price of $58.75.
Most Expensive Store: The most expensive store is the one that offers the highest price. In this case, the most expensive store is the one that offers a price of $70.00.
Average Price: The average price is the mean of the prices offered by all the stores. In this case, the average price is $56.43.

In conclusion, the data collected by Nikko shows that the prices of skateboards at the seven online stores vary significantly. The cheapest store offers a price of $58.75, while the most expensive store offers a price of $70.00. The average price is $56.43. This analysis can help consumers make informed decisions when shopping for skateboards online.

Based on the analysis, we recommend the following:

Shop at the Cheapest Store: If you are looking for the best deal on a skateboard, we recommend shopping at the cheapest store, which offers a price of $58.75.

This analysis has some limitations. The data collected by Nikko is limited to seven online stores, and it may not be representative of the entire market. Additionally, the prices may have changed since the data was collected. Therefore, we recommend verifying the prices before making a purchase.

Future research can focus on collecting more data from a larger number of online stores. This can help us understand the prices of skateboards in more detail and make more informed recommendations. Additionally, we can analyze the prices of other products to see if there are any patterns or trends.
