First night of my notice! Everything bad about the job now makes me happy, especially now I know the end is nigh.
Currently researching pop psychology essay, but it is annoying to research something your just going to slate for 1500 words. Considering personality typing as a topic, but there isn’t much recent stuff, except in management journals. Management love personality typing, especially in supermarkets! I remember first going to apply for a job at M&S, you couldn’t apply in store, you had to complete an online personality test (talent screening) first before you could have an interview.
The test had questions about how you would act in different scenarios, and the choice of answers were all acceptable things to do and extremly similar (e.g. you finish a task, do you – a)help busy collegue, b)ask supervisor what to do, c)recheck work). Anyway, I filled the questionnaire out and got rejected because I favoured the answers about organisation and efficiency over customer service, which seeing as I was applying for a job early mornings before the shop opened, I figured I was fine. Alas, I had failed. There was so many things about the questionnaire that just seemed weird, there seemed no way of of assessing it, or even telling which answer was correct!
A quick google later I have the answers and an interview and was employed within three days. I would love to meet who came up with the idea of having a very poor personality test as a screening process for interviews. Even a good personality test surely could not say who is better suited to stacking fruit and veg. Maybe if I’m stuck for work again I can use my psychology skills to examine the customer base in supermarkets, it’s always surprising to see the same elderly people come in every morning to buy a lime, a handful of grapes and a can of gin and tonic.
Anyway, back to researching this fun topic…
After losing all index related everything…twice…in a month, the decision to change hosting was an easy one. It’s just annoying to have to re-make all my wordpress jazz. Luckily I hadn’t had time to customise it too much!
However, I have back ups of my few posts, which I just stuck up, and are completely the wrong dates, so it looks like I got flu, did several assignments, went to work, recovered from flu and got new hosting in about 4 hours. Busy day!
Much less stressed now I have the weight of half my assignments off my back. Also, had good news relating to work. This weekend at the library won’t seem anywhere near as depressing as usual! Only a results section and a plasticity essay to go, which I’m more set with now. In a week I’ll be free!
Also, discovered Art Brut, much behind the times…where has my music brain been hiding the last few years
I seem to get a lot of hits to this post from people googling the phrase “unlikely due to chance”. In fact the majority of my traffic comes from this! (SEO worked well, even if it was by accident!) Before this post was probably the most un-useful thing to find if your googling this phrase, as it only consisted of myself moaning about assignments. Seeing as I am a geek for stats I shall explain the phrase so I can stop annoying people.
Basically, when doing statistics, everything is down to probability and chance. The probability of a coin flip is 50/50. There are two events that can happen “heads” and “tails” and both have an equal chance of happening. However, in most statistical analysis it will never be this simple, but what you will want to know is:
Has variable A had an effect on variable B?
How likely is it that the effects observed are due to chance? Could these results have just randomly been picked from a hat of possible results, so in fact there is no affect between variable A and variable B?
The point of conducting controlled experiments and then analysing the data is that you need to prove what you have observed is actually what you have observed. There is no point saying one number is bigger than the other and this proves something, as this could be just due to random chance. You need to prove your results.
A simple example:
Variable A (amount of sleep) and variable B (test score). Does the amount of sleep you have the night before a test improve the test scores?
A psychology student is conducting an experiment to see if the amount of sleep you have the night before a test improves the test score. There are two groups, one has their normal amount of sleep and the other group are prevented from sleeping.
On these results you can then perform the appropriate statistical test (in this case an unpaired t-test), and find out if the test scores are significantly different depending on the amount of sleep. You will be able to see if they are significantly different from the p value.
p values are the probability that a result happened by chance. In psychology for the p value to be significant it has to be p<.05. If you have a p value <.05 this means that there is less than 5% chance of getting the results by chance. Meaning that it is very likely that variable A is, in fact, having an effect on variable B and furthermore very unlikely that the result is due to chance. If the p value is not significant i.e. it is >.05. Your results could have happened by chance and it is likely that there is no effect between the two variables tested.
So…in conclusion “unlikely due to chance” is simply when you have tested variables and found a significant p value, p<.05, the results you have found are unlikely to be due to chance.
ORIGINAL POST – most dull
Finally back to the land of the existing people. I’d say land of the living and be cliche, alas having three large assignments to do is not what I would define as living. My desktop background is nothing more than a taunting ghoul. It consists of all my deadlines, on both my monitors, I’d love to crossed them all off and bask in front of the completed list, or at least pretend for a few minutes. Meh.
Unfortunately, due to my constant germ-age this month I am more behind than I would prefer and will be spending the next three days doing nothing but faux stats, learning theory and some kind of plasticity essay that I have no idea about yet. Not good. Though I have already spent a good 4 hours on my faux stats, it is done bar the fact it needs to be made into English and not just disjointed sentences.
Good news is I finally cracked and bought many digital downloads of David Devant and Mr.Solo, hopefully this will make my assignments much less painful. The joy of a new band I like, well, new to me anyway. Happiness!
