(3 marks)

(c) After the presentation, Mary decides to collect more views from respondents and sends them

each a questionnaire by postal mail, for which a name label is required. The name and sex of

each respondent are stored in a worksheet and part ofthe worksheet is shown below.

A B C D

1 Sex FirstName LastName Title

2 F May Chan

3 M John Wong

4 F Amy Ho

F and M in column A represent female and male respectively. Each name label should include

the title of each respondent before his or her name, for example, Ms May Chan, Mr John Wong

and Ms Amy Ho.

(i) Mary used the foUowing steps in a word processor to create the labels.

(1) Use ‘mail merge’ with columns, Sex, FirstName and LastName, as fields.

(2) Produce a merged document containing all the name labels.

(3) Use ‘find and replace’ in order to add the titles ofrespondents.

Instead of “Ms May Chan”, the label shows “Mrs Mray Chan”. Explain why.


(ii) By making use of formula(e) in the spreadsheet, describe how to add the titles of

respondents, ‘Mr’ and ‘Ms’, in column D of the worksheet.

(4 marks)

Mary uses spreadsheet software to store the responses from 40 copies of the questionnaire. Each

copy consists of 6 questions. The responses to the questions are coded as values: 1, 2, 3 or 4.

The following worksheet is used to record the responses.

A B C D E F G H I

1 Question

Questionaire

Q1 Q2 Q3 Q4 Q5 Q6

2 Copy 1 3 2 1 1 4

When some responses are missing, the corresponding cells in the worksheet are left blank (e.g.

D2). To calculate the total number of copies without any missing responses, firstly a formula is

entered into I2 and then copied into I3 to I41. Secondly, another formula, ‘=SUM(I2:I41)’

is entered into I43.


(d) Write down the formula in I2.

(2 marks)

(e) The mean response score of a question is defined as:

Sum of all values of the responses on that questionMean response score=

Number of response on that question

where the mean response score is correct to 1 decimal place.

A formula is entered into B43, and then copied into C43 to G43, to find the mean response

score for each question. Write down the formula in B43.
