Introduction

In this article, we will delve into the world of statistics and explore the data collected from the first 100 customers at a coffee shop. The data provides valuable insights into the preferences of coffee shop customers, including their preferred drink sizes and temperatures. By analyzing this data, we can gain a better understanding of customer behavior and preferences, which can be useful for businesses looking to improve their services and offerings.

Data Analysis

The data collected from the first 100 customers at the coffee shop is presented in the following table:

Drink Size	Hot	Cold	Total
Small	5	8	13
Medium	48	12	60
Large	22	5	27
Total	75	25	100

Drink Size Distribution

Let's start by analyzing the distribution of drink sizes among the customers. From the table, we can see that the majority of customers (60 out of 100) ordered medium-sized drinks. This suggests that the medium size is the most popular among customers, followed by large and small sizes.

Temperature Distribution

Next, let's analyze the distribution of drink temperatures among the customers. From the table, we can see that the majority of customers (75 out of 100) ordered hot drinks. This suggests that hot drinks are more popular among customers than cold drinks.

Correlation between Drink Size and Temperature

Now, let's explore the correlation between drink size and temperature. From the table, we can see that the majority of customers who ordered hot drinks (75 out of 100) ordered medium-sized drinks (48 out of 75). This suggests that there is a strong correlation between hot drinks and medium-sized drinks.

Chi-Square Test

To further analyze the data, we can perform a chi-square test to determine if there is a significant association between drink size and temperature. The chi-square test is a statistical test that is used to determine if there is a significant association between two categorical variables.

	Hot	Cold	Total
Small	5	8	13
Medium	48	12	60
Large	22	5	27
Total	75	25	100

The chi-square test statistic is calculated as follows:

χ² = Σ [(observed frequency - expected frequency)^2 / expected frequency]

where observed frequency is the number of customers who ordered a particular drink size and temperature, and expected frequency is the number of customers who would be expected to order a particular drink size and temperature if there was no association between drink size and temperature.

The chi-square test statistic is calculated as follows:

χ² = [(5-4.5)^2 / 4.5] + [(48-45)^2 / 45] + [(22-20)^2 / 20] + [(8-7.5)^2 / 7.5] + [(12-10.5)^2 / 10.5] + [(5-4.5)^2 / 4.5] = 0.11 + 0.09 + 0.10 + 0.09 + 0.09 + 0.11 = 0.58

The degrees of freedom for the chi-square test is (number of rows - 1) × (number of columns - 1) = (3 - 1) × (2 - 1) = 2.

The p-value for the chi-square test is calculated as follows:

p-value = P(χ² ≥ 0.58, df = 2) = 0.75

Since the p-value is greater than 0.05, we fail to reject the null hypothesis that there is no association between drink size and temperature.

Conclusion

In conclusion, the data collected from the first 100 customers at the coffee shop provides valuable insights into the preferences of coffee shop customers. The majority of customers ordered medium-sized drinks, followed by large and small sizes. The majority of customers also ordered hot drinks, followed by cold drinks. The chi-square test suggests that there is no significant association between drink size and temperature.

Recommendations

Based on the analysis of the data, the following recommendations can be made:

The coffee shop should consider offering more medium-sized drinks to cater to the preferences of the majority of customers.
The coffee shop should consider offering more hot drinks to cater to the preferences of the majority of customers.
The coffee shop should consider offering a variety of drink sizes and temperatures to cater to the diverse preferences of customers.

Limitations

The analysis of the data has several limitations. The data is based on a small sample size of 100 customers, which may not be representative of the larger population of coffee shop customers. Additionally, the data does not take into account other factors that may influence customer preferences, such as the time of day, the weather, and the location of the coffee shop.

Future Research

Future research should aim to collect a larger sample size of customers and take into account other factors that may influence customer preferences. Additionally, future research should aim to explore the correlation between drink size and temperature in more detail, and to identify the underlying factors that drive customer preferences.
