The reduced ability to have children is referred to as infertility. Infertility can be caused by the lack of ovulation, PCOS, age, stress, or a variety of other health conditions.
A graph that represents a population by age and sex is called a population pyramid. It typically displays age groups on the vertical axis and the population size on the horizontal axis, with one side representing males and the other representing females. This visual format allows for easy comparison of the distribution of different age groups between sexes, highlighting demographic trends and potential population growth or decline. Population pyramids can reveal important insights into the age structure and gender balance of a population.
The sampling method described is known as "cluster sampling." In this approach, the population is divided into distinct groups or clusters, often based on geographical or other natural groupings. A random sample of these clusters is then selected, and all individuals within the chosen clusters are included in the sample. This method is useful for efficiency and practicality, especially when dealing with large populations.
A bar graph is commonly used to represent population data, allowing for easy comparison between different groups or categories, such as populations of various countries or regions. Alternatively, a line graph can effectively show population trends over time, illustrating how a population has increased or decreased across different years. For more complex data, a population pyramid can visualize age and gender distribution within a population.
