FTD = Florists' Transworld Delivery. STD = Sexually Transmitted Disease.
Standard error A statistical measure of the dispersion of a set of values. The standard error provides an estimation of the extent to which the mean of a given set of scores drawn from a sample differs from the true mean score of the whole population. It should be applied only to interval-level measures. Standard deviation A measure of the dispersion of a set of data from its mean. The more spread apart the data is, the higher the deviation,is defined as follows: Standard error x sqrt(n) = Standard deviation Which means that Std Dev is bigger than Std err Also, Std Dev refers to a bigger sample, while Std err refers to a smaller sample
It's really no big deal. Within your first yer of periods it will spread out more. If not ask your mom or doctor.
sexually transmited dissease! umm...probablly!..but..who knows! :)
For z-score calculation, mean and std deviation must be given.
There is no STD that mosquitoes spread.
Sex. It is an STD.
Unprotected sex.
it can spread STD's and cause pregnancy
some are flu , HIV , std
Do you mean an STD as a sexual infection? If so, it didn't "come into practice" it has always been around and spread ( still is spreading) with unprotected sex.
Still a risk of STD.
reduce the spread of STD's protection f the environment. education for women and girls.
You have aids... maybee
depends upon the std but most likely , yes, almost all can be spread by what is termed "heavy petting" i.e. when genitals touch , this includes fluids from genitalia.
If you have missed your period for two months, you are probably pregnant. You could take a home pregnancy test, but you should see a doctor and if you think you could have an STD, you should see a doctor immediately anyhow.
Yes it is possible to get an infection or even STD during menstruation.
