Answer 1:

The below table describes the frequency distribution table for the unwantedcalls received in a day by each respondents. The respondents are a sample of

25 professionals working in Dubai, UAE. Refer appendix for the details of

the respondents.

Mean = 3.60 Standard Deviation = 1.91

Answer 4:The survey for this assignment has been conducted using the data sampling

method. The type of random sampling method used for this survey is the

Stratified sampling method. The sample data was picked up from the

geographical area where I reside and from that divided it into different units

on the bas is of the profess ion. Care has been taken to randomly pick up the

people from each of the units .

Limitations in this survey -

- Restricted to sampling people residing in Dubai and Sharjah.

- Lack of questions whether the contact number of the respondent is new or

accessible to the sources used by the tele-callers.

- The unwante d call s are not known whethe r they are from telema rket ingcompanies or unknown private callers.

Results

The mean is 3.60

The Standard Deviation is 1.91

We can observe from the standard deviation, that the data values distributed

around the mean is neither very wide nor close. Assuming that a normal

dis tr ibution of the data, i t is apparent that 68% of the respondents receive

calls within 2 cal ls of the mean and almost 95% of the respondents receive

calls within 4 calls .

As mentioned above, the survey definitely lacks some additional inputs which

would have been important to substantiate the results. However, after



collecting further information on the respondents, it has been noted that

unwanted calls are definitely received by the professionals. From the data set

collected, two of the respondents have received 0 unwanted calls . The reason

was due to the fact that their contact numbers very new and defini tely not

access ible to the tele-cal lers . Moreover, they have not received cal ls from

unknown private callers so far on the new contact number.

Some of the data items show that they have received more calls . The reason is

related to their social s tatus in the environment. For e.g. they have registered

in many marketing schemes where they have provided their contact numbers.

Hence the numbers of cal ls are more than everyone else. Few of them have

their presence in the region for a long time and this attracts more callers due

to the exposure in some way or the other which are potential sources for the

tele-marketing companies.



Answer 5:

There a lo t of ins tances where unwanted cal ls becomes annoying, whether they are one or more than one call. The results show that most of the

respondents receive one or more than one unwanted cal ls . These cal ls are a

problem especially when they are received during meetings or some

inconvenient times. The results definitely show that the respondents receive

unwanted calls during meetings and at certain inconvenient times.

Calls received during meetings

Receiving calls during meetings are avoidable. Hence while we say that

unwanted calls are a problem, the same time it is questionable as to why such

calls are received during meetings especially when the mobile phones are

supposed to be switched-off.

There are some meeting etiquettes especially in the usage of mobile phones -

• Mobile phones must be switched-off or kept on silent mode during

meetings

• Do not use phones to make cal ls during meetings . If any urgent cal ls

are to be made, then the person has to go outside the meeting room if it

is appropriate and then make the call.

• Mobile phones must not be kept in vibrator modes and kept on the

table. Vibrators are most annoying not only to the receiver but also to

the other participants in the meeting.

• If any impor tant call s are coming , then the partici pant must excuse

himself/herself and inform the caller to call back.

Tele-Calls



In some cases, the tele-calls are important calls because it may give

information about some promotional packages. The tele-calls may be

notification to the subscribers of certain services informing them about

packages which are suitable and cost effect ive. Some of the tele-cal ls are

intended to inform about the expiry of service ut i l i ty services . We cannot

term as unwanted cal ls , but of course we may not expect such cal ls during

meetings or any inconvenient times. At times some tele-calls have helped to

enroll for some schemes which are very useful and money savers.

Debt collector’s call

Some calls from debt collectors can definitely be annoying especially when it

is enquiry about somebody else’s debt. The reason for receiving such call is

that our names have been provided as the references to the bank.

Incorrect dialer codes used

In some cases, there are calls which are not intentional. Especially in UAE,

there are mobile numbers which start with 050 or 055 as the dialing code and

then a seven digi t number. By mis take if the dialer does not use the correct

dialer code, then the call will end up to an unintended receiver.

Steps to be taken to reduce unwanted calls –

• Reply s traight that you are not in teres ted in the cal l and cal l ing at an

inconvenient time is not acceptable. This will reduce follow-ups

further.

• Permanently block unwanted calls. There are some acts to obstruct

unwanted calls . Some countries have a clear and precise policy to filter

tele-calls to its people.

• According to the “Federal trade commission ( www.ftc.gov) ”, the banks

are not supposed to call for any debt collection during office hours or

when the banks are informed not to call during office hours.

• Switch-off phone calls during meetings or keep it in silent mode.



• Maintain phone l is t of al l known sources . Rest you can consider as

unknown numbers and can discretely answer if you feel is important.
