There seems to be an issue with the data, possibly due to incorrect formatting or the presence of non-numeric values in the

`Revenue`

column. This has led to incorrect calculations of total revenue by product category. It's recommended to check the data for inconsistencies or formatting errors and correct them for accurate analysis.Show code

The investigation into the

`Revenue`

column revealed the presence of non-numeric values, including `NaN`

and `#VALUE!`

, which are causing issues with calculations. Here's a summary of findings:- Non-numeric values were found in multiple rows.
- One specific non-numeric value identified is
`#VALUE!`

in the`Eyewear (Sports)`

category. - There are also rows with
`NaN`

values in both the`Product Category`

and`Revenue`

columns.

To proceed with accurate calculations, these non-numeric values need to be addressed, either by removing these rows or converting them to a numeric format where possible.

Rows with non-numeric values in the

`Revenue`

column have been successfully removed, and the `Revenue`

column has been converted to numeric in the cleaned dataset. This prepares the data for accurate financial calculations and analysis.Show code

After cleaning the data by removing rows with non-numeric values in the

`Revenue`

column, we recalculated the total revenue by product category. Here are the results:**Accessories**: $11,011**Apparels (Lifestyle)**: $135,810**Apparels (Sports)**: $455,890**Bags & Bag packs**: $57,310**Eyewear (Lifestyle)**: $176,695**Eyewear (Sports)**: $690,807**Footwear**: $94,145**Helmets**: $22,750

This provides a clearer picture of the revenue generated by each product category.

Plot

We visualized the total revenue by product category using a bar chart. This visualization clearly shows the revenue distribution across different categories, highlighting which categories generate the most revenue. The

`Eyewear (Sports)`

category stands out as the top revenue generator, followed by `Apparels (Sports)`

, and `Eyewear (Lifestyle)`

. Other categories contribute to the total revenue to varying degrees, with `Helmets`

and `Accessories`

generating the least revenue among the categories listed.Research Question: Is there a significant difference in the average sales revenue between different product categories?

To answer the research question about the significance of the difference in average sales revenue between different product categories, we'll conduct an ANOVA (Analysis of Variance) test. This statistical test helps determine if there are any statistically significant differences between the means of three or more independent groups. In this context, the independent groups are the different product categories.

We'll first ensure the data is suitable for an ANOVA test, then proceed with the test to analyze the differences in average sales revenue across product categories.

The ANOVA test resulted in a statistic of approximately 161.25 and a p-value of approximately $3.91 \times 10^{-222}$. This very small p-value indicates that there is a statistically significant difference in the average sales revenue between different product categories. Therefore, we can conclude that not all product categories generate the same amount of revenue on average, supporting the need for further analysis to identify specific differences between categories.

The hypothesis you're referring to is typically tested using an ANOVA test, which we just performed. The null hypothesis for an ANOVA test states that there are no significant differences among the group means, which in this context refers to the average sales revenue among different product categories.

Given the results of the ANOVA test, with a p-value of approximately $3.91 \times 10^{-222}$, we reject the null hypothesis. This means there is a statistically significant difference in the average sales revenue among different product categories, contradicting the stated hypothesis.
