Context: Reading and Spelling age score sheet (eg. a student takes a test and it tells them what their 'reading age' is- 14.03 would be 14 years and 3 months). Ideal Outcome: Need to calculate progress for each student + average progress for each year group. Issue: Formula to convert years and months (eg. 15 years and 4 months 15.04) to months (eg 184 months) works in columns J and K (converting columns C and D) but does not work in columns N and O (converting columns F and G) - ie N2 should be 12.7 in months, which would be 12 x 12 + 7, which would be 151, but formula says 214?

Column A shows the number of times a particular article was shared online Column B shows the number of words that the article had. The question is - Were pieces over 1,000 words (num_words) shared more, on average (total_shares)?

I'm dealing with an advanced excel pivot table problem. Please help me assign the following structure to the pivot table: The rows should have the first level of the variable referred to if the student belongs to a rural area or an urban area and as a second level if a family of more than 3 people belongs or not. The first column should answer if it is more common for a student to belong to a house with more than 3 inhabitants in a rural area compared to an urban area (As an example, it should show that 72.27% of students from urban areas belong to households with more than 3 inhabitants). The second column must show if the students' final grade (variable G3) is the same for households with more or less than 3 inhabitants, disaggregated by rural and urban area (As an example, it must show that the final average of the students who come from home with 3 or less students and who live in urban areas is 10.90).

Hi there, I am looking for help with a formula. Unfortunately I cannot share much of the document so I have deleted some of the values. I have left one column that I am using for the sake of example because I realize that the formula I use will be the same for each row of the table I want to fill in. There are two tables on this sheet. My goal is to fill in the top one using the values from the bottom one (considering that it will be filled in). I want to use the average function to calculate the average quarterly revenue. Thus far, I have done this by using this formula as an example: =AVERAGE(H92:H94)-AVERAGE(H80:H82) This formula takes the average of one quarter and finds the difference from the same quarter a year previously. I do not know how to extend this across columns, so I have had to input each value manually in each column. Can you please provide assistance?

How’s it going? Here I have a table (let’s call it Table 1) that would ordinarily be populated, but I cannot share the values unfortunately. To the far right you can see another little table I used to find the average values for each category and year using AVERAGEIF and also basic formulas for year on year changes (let’s call it Table 2). On Sheet2 is the transposed version of that table (Table 3), which is the one I want to populate using a formula linking it to Table 1 (eliminating the need for Table 2). I think the formula to use might be HLOOKUP, but I could be wrong… maybe HLOOKUP and AVERAGEIF. I would really appreciate your help on this. Thanks!

These 3 questions need to be answered please. I can provide the data set when necessary. Question 1: 1.) During a TYPICAL MONTH of school, how often do you skip class? 1: Never 2: Rarely 3: Sometimes 4: Often 5: Almost Always i. Construct a histogram of the numerical responses for each of the first, second, third and fourth years. For each histogram, identify which response is the most frequent and identify and differences or similarities you observe. ii. Perform at the 5% significance level the one-way ANOVA test to compare the population means for each of the 4 years of data. Should we reject or not reject the claim that there is no difference in population means between each year? Question 2: Is there a linear relationship between frequency of skipped classes and grade average? Consider the data in columns C-F which provide grade average in years 1-4 respectively and the data on how often classes are skipped that you worked with in Questions 1 and 2. a) Use Excel to find the correlation coefficient for average and classes skipped for each of the four years. b) Identify the year that has the strongest linear relationship. Using the data for this year, use Excel to obtain a full regression analysis including a scatter plot with regression line plotted, regression line equation, coefficient of determination. (Hint: Use classes skipped as the explanatory variable.) c) Based on the correlation coefficient and the analysis in b), do you feel that frequency of classes skipped is a good predictor of grade average for this year? Explain by making reference to relevant numerical measures where appropriate. Question 3: We will now look at whether or not a relationship exists between grade average in third and fourth year. a) Use Excel to find the correlation coefficient for this data. b) Use Excel to obtain a full regression analysis as in #2 b) above. (Hint: Use average in third year as explanatory variable.) c) Test the claim that there is a positive linear correlation between the two sets of grades at a 0.01 level of siginficance

How’s it going? I had a previous session but time ran out and I got no reply.

Add Minimum Cost and Maximum Cost rows that are formatted similarly to row 50 (Average Cost row). Use functions to calculate the minimum and maximum costs for the systems purchased. Convert the Initial Cost data including the Average Cost, Minimum Cost, and Maximum Cost, and the Depreciated Value data from a generic number to accounting format with no decimal places. Copy the average, minimum, and maximum functions to the Depreciated Value columns. Merge and center the title “Desktop & Laptop Systems Inventory & Depreciation” above all of the columns with data. The CEO has asked you use conditional formatting to create an easy visual on the spreadsheet of any device that is near the end of its useful life. Utilize conditional formatting for all columns that contain a depreciated value of less than $500 they will appear red. Create a pie chart to show the initial cost totals by department. You may create a set of summary data to the right of the current data to use for the creation of your chart.

You are going to roll four twenty-sided dice. If the rolls total to 20 or less, roll two more twenty-sided dice and add that to the total. For instance, if the total of my four die rolls is 32, then that is the score of the game. If the total is 17, then I roll two more dice and add that to the total. If these two bonus dice total 20, then the score of that game is 37. Of ten thousand games, what is the average score? (choose the closest range)
