Box-plots show median, quartiles, min, and max, not mean!

I think all of them could be true, but I have my doubts.

Wait, are we sure about that frequency table? Seems off.

Totally agree, but box-plots don't show mean, just median!

Histograms show frequency with rectangle height, that's true.

I feel like all of them could be true, but I have a nagging feeling about the box-plot one.

I practiced a similar question about frequency tables, and I think the data set given can definitely be represented in a frequency table.

I’m not sure about the box-plot statement; I thought it included quartiles but not the mean.

I remember that in a histogram, the height of the rectangles does represent the frequency, so that one seems true.

I think I've got a good handle on this. I'll methodically go through each statement, considering the information provided in the question and my knowledge of data visualization techniques. I'm feeling confident I can determine which ones are not true.

Okay, let's see. The first statement about the height of the rectangles in a histogram seems straightforward, but I'll double-check that. The other two statements seem a bit more complex, so I'll need to really analyze those.

Hmm, this looks like a tricky one. I'll need to carefully review the information provided and think through each statement to determine which ones are not true.

I'm a bit confused by the box-plot chart statement. I'll need to refresh my memory on the typical components of a box-plot to make sure I understand that one correctly.

This question seems a bit tricky, but I think I can figure it out if I break it down step-by-step.

Okay, I've got a strategy for this. I'll think about factors like latency, scalability, and proximity to the IoT devices to determine the most suitable location.

Honestly, I feel like option C might just be an oversimplification. Surely there must be a better way than just making fewer requests, right?

I'm feeling confident about this one, but I'll keep my sense of humor just in case.

I hope I don't accidentally choose the 'all of them' option, that would be too easy!

User 2: I agree, option A is definitely not true.

User 1: I think option A is not true.

Oh boy, I better double-check my understanding of histograms and box plots.
TR

User 3: Statement 2 is also not true, a box-plot chart does not show Mean and Maximum values.
MA
Mayra

The frequency table doesn't match the data, so option II is not true.

User 2: I agree, the height of each rectangle in a histogram does not equal the frequency of the interval.
AV
Avery

Box plots actually show Median, Quartiles, and Outliers, not Mean.
JA
James

Don't worry, histograms show frequency by the height of the bars.
DE

User 1: I think statement 1 is not true.
EL

I believe statement 2 is also not true. A box-plot chart does not always show Mean, Median, Upper Quartile, Minimum, and Maximum.
