Scatter plots are graphical representations that display the relationship between two quantitative variables, with each point representing an observation in the dataset. A trend line, often a linear regression line, can be added to these plots to illustrate the overall direction or trend of the data points, helping to identify patterns or correlations. By analyzing multiple scatter plots, one can compare different datasets or relationships, making it easier to draw insights from the data. The combination of scatter plots and trend lines is a powerful tool for visualizing and interpreting statistical relationships.
Anomalous data points on a graph are commonly referred to as "outliers." These are values that deviate significantly from the overall trend or pattern of the dataset, often indicating variability in the measurement or potential errors. Identifying outliers is crucial for data analysis, as they can influence statistical results and interpretations.

A vertical trend refers to a consistent upward or downward movement in data points over a specific period, often illustrated in charts or graphs. This trend indicates a significant change in a particular variable, such as sales, stock prices, or website traffic, showing how it evolves over time. Vertical trends can help analysts identify patterns, make forecasts, and inform strategic decisions.
It is the description of a slope of a line which connects from many points you mark to show a way that your graph data may increase or decrease. If it is decreasing, you have a downwards trend. If it is increasing, you have an upwards trend.

Outliers in a line plot are data points that significantly deviate from the overall trend or pattern of the other data points. They can appear as points that are much higher or lower than the surrounding values, indicating unusual or exceptional cases. Identifying outliers is important as they can influence statistical analyses and interpretations. In a line plot, outliers may suggest anomalies, errors in data collection, or unique events warranting further investigation.
