Now we've met our guys it's time to introduce our gorgeous girl. This is Jojo and she's from Somewhereorother!

...cue music and very loud wolf whistles and applause

more loud applause and wolf whistle from the audience.

Hold on a minute there Jojo, I haven't introduced you yet!

You don't half make me feel like Cilla. I won't sing though.

So Contestant number 1, what's your name and where do you come from?

or should that be sole attention?

I think Jojo should abandon her appointment system and give Coastman her soul attention,

I think Jojo's still giving appointments Mr Chipz, there may be slot waiting for you. Just between you and me, you won't tell Coastman, will you?

It's just one person's opinion. My two best mates (who are very like me) often talk fondly of the time they spent doing their PhDs a few years ago and have heartily recommended I do it.

Obviously it has its up and downs but I'm looking forward to it.

I can say that on the male side of the fence, 30s are much less intimidating as we can use our experience to attract 20 something females. Also, the pressure of a 30 something girlfriend is that they often have an agenda based around their biological clocks. The 20 something girlfriend buys the male of the species some time.

Blimey Jojo, can't wait to be 30?

fantastic, can we have an after-report like your last one Jojo?

Great stuff - a bit of reverse psychology. Lamb would be proud!

In terms of doing surveys, I take it you mean short questionnaires. In this case, the required number of questionnaires is determined by how you intend to analyse the data. For instance, if you only intend to slice and dice the whole sample then you'll need fewer, say 50 interviews.

If you intend to subdivide the respondents into groups and renalyse the data you will need alot more, depending on the level of detail you require in each.

Another caveat is where you're investigating a topic in which few people you survey are able to comment on the really juicy questions. So for example, if you survey 100 people, but only 10 people are able to answer a certain question you're not going to learn much. So a much larger sample is required.

They teach them in industry as well. I've made a career out of blaming someone else if something goes wrong. A particular favourite is to blame the client.
