measuring variation Flashcards
what is interspecific variation?

why does interspecific variation happen?
different genes causing differences in physical traits, adaptations, habitats, etc. and environmental factors like climate, diet, lifestyle,
what is intraspecific variation mean?
variation between individuals within a species
why does intraspecific variation happen ?
different alleles (gene variants) and environmental factors
explain random sampling?
Randomly generating coordinates across an area to prevent sampling bias.
Collecting samples from these random coordinates to represent the population.
Repeating this several times as a large sample size minimises the effects of chance.
Analysing the data collected to identify any relationships.
what is the mean?
The sum of the sampled values divided by the number of values
what is the median?
The central or middle value of a set of values.
what is the mode?
