What are the average prices of the commodity across all selected markets?

Show code

The average price of the commodity across all selected markets is 51.35 units.

How do prices vary across different markets for the commodity?

Continue the analysis

Show code

The average prices of the commodity across different markets are as follows:

Market A: 49.2 units
Market B: 64.4 units
Market C: 52.4 units
Market D: 39.4 units

This shows that prices vary significantly across markets, with Market B having the highest average price and Market D the lowest.

Is there a correlation between the prices of the commodity in the different markets?

Show code

The correlation analysis between the prices of the commodity in different markets resulted in a matrix with NaN values outside the diagonal. This outcome indicates that there's no direct data available to compute correlations between different markets within the provided dataset. Each market's prices are only correlated with themselves, as expected, showing a correlation coefficient of 1.0 for each market with itself and no calculable correlation between different markets due to the structure of the dataset.

Are there any outliers or anomalies in the dataset that require further investigation?

Show code

The boxplot analysis of prices by market reveals the following insights regarding outliers or anomalies:

Market A: No significant outliers observed.
Market B: No significant outliers observed.
Market C: No significant outliers observed.
Market D: No significant outliers observed.

Overall, the dataset appears consistent across the different markets without any apparent anomalies or outliers that require further investigation.

Perform a statistical analysis to identify any significant patterns in the dataset

Show code

The statistical analysis of the dataset reveals the following key points:

Count: There are 20 price entries in the dataset.
Mean: The average price across all markets is approximately 51.35 units.
Standard Deviation: The prices have a standard deviation of approximately 12.39 units, indicating variability in the prices.
Minimum and Maximum Prices: The prices range from 26 to 72 units.
Quartiles: The 25th percentile is at 43.5 units, the median (50th percentile) is at 51.5 units, and the 75th percentile is at 61.25 units.

This summary indicates a moderate spread of prices across the dataset, with a central tendency around the mid-50s. The range and standard deviation suggest variability in prices, but without extreme outliers.

Can we conclude at a 5% level of significance that the average price of the commodity is the same in all four markets?

Show code

The one-way ANOVA test results in a F-statistic of 6.44 and a p-value of 0.0046. Given a significance level of 5% (or 0.05), the p-value is less than 0.05, indicating that we can reject the null hypothesis. Thus, we conclude there is a statistically significant difference in the average prices of the commodity across the four markets.
