Accepted Answer

Hello and welcome back, everybody. The next question says A survey asks which of the following do you find most challenging when working from home. Responses are staying focused, managing time, avoiding distractions, and communicating with co-workers. Explained why these results should not be shown as a pie chart. The responses are percentages that sum to 100%. The responses are numerical and require a scatter plot. The responses are continuous data. Or D the responses are not mutually exclusive. Well, right away you can rule out choices B and C, because the responses are not numerical. Oh, but not numerical, and the responses are not continuous data. Continuous data would be as if your response could be something like How many hours on average do you spend working, you know, when you're working from home. And that could be this continuous stream. It isn't just one hour, two hours, it could be, you know, 1.3 or 5.4, or something like that. But here, we just have categories. So we got A and D, and choice A describes what you would use a pie chart for. A pie chart would reflect parts of a whole that's some to 100%. So, since we're supposed to explain why the results should not be shown as a pie chart, this would not be an explanation, because this would describe why it should be a pie chart pie chart. So our answer just by elimination is going to be choice D. The responses are not mutually exclusive. You could find avoiding distractions and managing time to both be the most challenging things. Now note this question could be formatted in a way that the percentages would add to 100%. If you said which of the following do you find most challenging, and then said, choose only one, then you could have parts of a whole at sum to 100%. Everyone can choose only one. Your answers could be broken down into these percentages. But it doesn't say choose only one, and we're told they should not be done as a pie chart. So that would imply that people could pick more than one answer. So the responses would not sum to 100% if they're not mutually exclusive, because that means people could pick more than one answer. So again, our question said, there's a survey, the question is which of the following do you find most challenging working from home? And responses are not numerical. They are descriptions like staying focused, managing time, avoiding distractions, communicating with co-workers, and we're supposed to explain why these results should not be shown in the pie chart. And our answer is choice D, the responses are not mutually exclusive. See you in the next video.
