Esri EADP19-001 Exam - Topic 10 Question 36 Discussion

Actual exam question for Esri's EADP19-001 exam

Question #: 36
Topic #: 10

An ArcGlS user has a point feature class and needs to determine whether there are any spatial outliers. For this project, a spatial outlier is defined as any feature that is greater than one standard deviation from the mean center of the features.

Which Spatial Statistics geoprocessing tool should be used to accomplish this task?

AAverage Nearest Neighbor

BCentral Feature

CMean Center

DStandard Distance

I’m surprised there’s no tool specifically for outliers!

I feel like the Average Nearest Neighbor might not apply here since we're looking for outliers based on distance from the mean, not proximity to other points.

I practiced a similar question, and I think the Central Feature tool is more about finding the central point rather than identifying outliers.

I'm not entirely sure, but I remember something about standard deviations being involved. Could it be the Standard Distance tool?

I think we need to find the mean center first, so maybe the Mean Center tool is the right choice?

Hmm, I'm not sure if Average Nearest Neighbor is the right approach here. That's more about clustering, right? I think I need to review the spatial stats tools again.

I'm pretty confident the answer is D. Standard Distance seems like the best tool to calculate the distance from the mean center and flag any features beyond one standard deviation.

I'm a bit confused on this one. Is the Mean Center tool the right choice, since it finds the central feature? Or is that not specific enough for identifying outliers?

Okay, I think the Standard Distance tool might be the way to go here. It calculates the standard distance around the mean center, which could help identify features outside that threshold.

Hmm, I'm a bit confused. Should we be looking at the Import definition instead? Maybe updating that to include a notification email address could help us identify the bad data rows.

I'm a bit confused by this question. There are a few options that seem relevant, like the Delphi technique or qualitative forecasting. I'll have to carefully read through the details to figure out which one best matches the description.

Okay, this looks like a pretty straightforward capital budgeting problem. I'll need to calculate the net cash flow for the 10th year, which will involve projecting the revenues, costs, and depreciation.

This question is making my head spin like a top! Maybe I should just use a Ouija board to figure out the answer. Or perhaps a crystal ball would work better for spatial analyses.

Hold up, is this a trick question? I mean, if we're looking for outliers, wouldn't the Average Nearest Neighbor tool be the way to go? It's like finding the black sheep in the herd, right?

Interesting problem. I'm not sure Standard Distance is the right tool though. Wouldn't Mean Center be a better choice to first find the mean center, and then we could use that to identify the outliers?

I agree with Fausto. Mean Center calculates the center of the features, so it can help identify spatial outliers.

Hmm, the key here is to identify spatial outliers. I think Standard Distance would be the way to go since it calculates the standard distance around the mean center, which could help identify the outliers.
