Question
Question 1
Why might a user want to manipulate the page set up options for a spreadsheet (as compared to a Word document)? For example, what is the point of changing orientation in a spreadsheet’s page setup?
Question 2
Imagine you are working with a word document that is meant to track the ages of all students in a high school. The sheet contains their name, age, sex, and a few other pieces of information. You want to know how many male students there are for each age group and how many female students there are. However, some students didn’t provide their ages (and thus a “0” is entered for their age), and others gave unusual answers (like “-42” or “100”). Using a basic COUNT function, sorting, and/or filtering how could you use conditional formula logic to get an approximate count of student sex by age, ignoring these outliers?
Question 3
When does it make sense to use a filter in a spreadsheet that’s being used for data analysis, particularly one being shared with others?
Question 4
Excel, like Word, allows users to customize the ribbon tabs and groups (Data, Home, Insert, etc.), hiding, re-organizing, or even allowing the creation of entirely new groups. Why might a user be interested in this feature?
Question 5
You are looking at a spreadsheet that shows the results of two surveys: The first survey indicates that 10.5 percent of all people surveyed were 25 years old. There were 581 people in the survey, and there is a slight margin of error in answers. The second survey included responses from about the same number of people and produced 60 respondents who claimed to be 25. Rounding to the nearest whole number, write the full mathematical formula that would take the raw numbers and show how many people total (across both surveys) are aged 25. And assuming all future surveys sought responses from the same general group, how many more people would you need to survey to identify 300 total 25-year-olds? answer in a highschoolers words

### Question 1
A user might want to manipulate the page setup options in a spreadsheet for a few reasons. One main reason is that spreadsheets often contain a lot of tabular data that might be better displayed in portrait or landscape orientation depending on how much data there is. For instance, if a spreadsheet has many columns with data, using landscape orientation can prevent the data from being cut off, making it easier to read and print. It's about fitting the information on the page appropriately to ensure everything is visible and looks organized.
### Question 2
To count how many male and female students are in different age groups while excluding outliers (like “0”, “-42”, or “100”), you can use an IF statement combined with the COUNT function. For example:
1. Create a formula that checks if the age is valid (e.g., greater than 0 and less than a reasonable max age, such as 120).
2. Use COUNTIFS to count male and female students based on these criteria. Here’s a basic idea:
```
=COUNTIFS(AgeRange, ">0", AgeRange, "<120", SexRange, "Male")
=COUNTIFS(AgeRange, ">0", AgeRange, "<120", SexRange, "Female")
```
Replace `AgeRange` and `SexRange` with the actual ranges of your data. This way, you ignore the invalid ages when counting.
### Question 3
Using a filter in a spreadsheet for data analysis makes sense, especially when you're sharing the spreadsheet with others, because it helps everyone focus on specific data without being overwhelmed by the whole dataset. For example, if you're presenting data about student performance, filters can allow others to view only the information relevant to them, like seeing scores for just one class, which can lead to better discussions and insights without sorting through unnecessary information.
### Question 4
Customizing the ribbon tabs and groups in Excel can be really helpful because it allows users to have quick access to the tools they use most often. If someone frequently uses specific functions or tools, they can arrange them in a way that makes their workflow smoother and more efficient. This personalization can save time and reduce frustration since users don't have to search for commands buried in menus.
### Question 5
To find out how many people are 25 years old from both surveys, you can write the formula like this:
1. From the first survey, find out how many people are 25:
\( \text{Count from Survey 1} = 0.105 \times 581 \)
This equals about 61 people (when you calculate 0.105 * 581 and round).
2. From the second survey, you know 60 people said they were 25.
So, the total count would be:
\[
= 61 + 60 = 121
\]
Now, to find out how many more people need to be surveyed to hit a total of 300:
\[
300 - 121 = 179
\]
This means, assuming similar results, you would need to survey enough people to find 179 more people who are 25 years old to reach your goal of 300 total 25-year-olds. If the same percentage holds, you would need to survey around:
\[
\frac{179}{0.105} \approx 1705.71
\]
So, you would need to survey at least 1,706 more people if the response rate stays about the same.
