A math teacher gave a math test. Interpret the scatterplot to determine which point is the outlier. (1,78) (4.5, 97) (2.5, 87) (0.5,45)
To determine which point is the outlier in the scatterplot, we need to observe any point that significantly deviates from the general trend of the other points.
Using the given coordinates:
(1,78)
(4.5, 97)
(2.5, 87)
(0.5,45)
By examining the values, we notice that (0.5, 45) seems to be significantly different from the other points, as all the other points have much higher y-values. Therefore, (0.5, 45) is the outlier in this scatterplot.
To interpret the scatterplot and determine the outlier, we need to identify the point that is significantly different from the others.
Looking at the given points: (1, 78), (4.5, 97), (2.5, 87), and (0.5, 45), we can examine their values and identify the outlier.
The data point (0.5, 45) appears to be the outlier as it has a significantly lower y-value compared to the others. The x-value does not necessarily determine outliers in this case, as we are looking for a point that deviates from the general pattern of the other data points.
To determine which point is the outlier in the scatterplot, we need to understand what an outlier is in the context of data points. In statistics, an outlier is a data point that significantly deviates from the average or expected values of a dataset. It is an observation that lies an abnormal distance from other values.
To interpret the scatterplot, we can plot the given points on a coordinate system. Let's plot the points (1, 78), (4.5, 97), (2.5, 87), and (0.5, 45) on a graph.
- Plot (1, 78): Locate the point (1, 78) on the graph. This means that the x-coordinate is 1 and the y-coordinate is 78. Mark this point on the graph.
- Plot (4.5, 97): Locate the point (4.5, 97) on the graph. This means that the x-coordinate is 4.5 and the y-coordinate is 97. Mark this point on the graph.
- Plot (2.5, 87): Locate the point (2.5, 87) on the graph. This means that the x-coordinate is 2.5 and the y-coordinate is 87. Mark this point on the graph.
- Plot (0.5, 45): Locate the point (0.5, 45) on the graph. This means that the x-coordinate is 0.5 and the y-coordinate is 45. Mark this point on the graph.
After plotting these points, examine the distribution of the points. Look for any point that appears to be significantly different from the rest or one that is much further away from the other points.
Based on the scatterplot, it appears that the point (0.5, 45) is the outlier. This point is noticeably lower and further away from the other points compared to the rest.
Remember, identifying an outlier is subjective, and further statistical analysis is often required to determine whether a data point is statistically significant as an outlier.
A teacher took an anonymous survey in one class and then posted the students’ heights and weights on a scatterplot. What point is the outlier?
(1 point)
