Math Problem Statement
Dresser un tableau croisé de deux caractères à partir d'un fichier de données.
Solution
This exercise involves analyzing a table with a cross-tabulation of two characteristics. Let's break it down step by step:
Given Table:
Femmes | Hommes | Total | |
---|---|---|---|
Moins de 40 ans | 12 | 17 | |
Plus de 40 ans | 5 | ||
Total | 40 |
Questions:
-
Quels sont les deux caractères étudiés dans ce tableau ?
- The two characteristics being studied in this table are age (less than 40 and more than 40 years old) and gender (women and men).
-
Donner le nombre d'employés de moins de 40 ans.
- The number of employees under 40 years old is the total for the first row:
.
- The number of employees under 40 years old is the total for the first row:
-
Recopier et compléter ce tableau.
Let's complete the missing values:
Femmes | Hommes | Total | |
---|---|---|---|
Moins de 40 ans | 12 | 17 | 29 |
Plus de 40 ans | 4 | 5 | 9 |
Total | 16 | 22 | 40 |
- The number of women is , and the number of men is .
Would you like further explanations on how to complete the table or any specific details on the questions? Here are some follow-up questions to extend this problem:
- How can you calculate the percentage of men and women in each age group?
- What is the total percentage of employees under 40 years old?
- If there were 10 more employees over 40, how would that change the table?
- Can you create a graphical representation of this data, such as a bar chart?
- What are the implications of having more employees under 40 than over 40 in terms of workforce planning?
Tip: Cross-tabulation tables are useful for visualizing the relationship between two categorical variables, making comparisons much clearer.
