Answer:

Various brands of nail polish utilized by Sarah.

Explanation:

In conducting an experiment, two variables are assessed; these are the independent variable and the dependent variable. The variable that is altered consistently to observe its effects is identified as independent variable while the one under examination is termed the dependent variable.

In this scenario, Sarah aims to determine which nail polish brand lasts longest without chipping. Thus, the diverse brands of nail polish she experiments with are designated as the independent variable.

11111nata11111 [2571]
The table related to this query lacks clarity, and I have provided a more detailed version of the data. The correct answer is BAR GRAPH. A bar chart or graph is a way to represent or display statistical information. Bars are oriented either horizontally or vertically to convey data. A bar graph is useful for comparing values across different categories, with the length of each bar indicating the magnitude of the data measured. The question's data describes a comparison between critically endangered species and those that are endangered or vulnerable in terms of percentage across various species types. In the BAR GRAPH, the x-axis will show the diverse species types, while the y-axis will represent the percentage (%) of endangered or critically endangered species. Two distinct bars, differentiated by color, will indicate whether the species is endangered or critically endangered.
