What are the three measures of Central Tendency—define or give me an example of each one for me.

Mean is arithmetic average of set of scores found by adding all scores together and dividing by the number of scores.

Median represents a halfway mark in the data set, with half of scores above and half below.

Mode refers to the score that occurs most frequently, and it is easy to determine by looking at a histogram. (Most frequently occuring scores in a set of scores.

Mean, Mode, and Median are all variables

What does variability mean?

Scores vary. Variability refers to the extent to which they differ from one another or from their mean.

The differences are measured using a standard deviation.

In the ideal curve, 95% of the scores will fall within how many standard deviation of the mean?

Within 2 standard deviations

Within three standard deviations.

What is epigenetics?

The study of gene-enviroment interactions in the production of phenotypes

The probability that two people share the same allele from a common ancestor.

What could that result in for identical twins?

Having identical genotypes does not guarantee identical phenotypes, or observed characteristics.

Having identical genotype's guarantees identical phenotype's.

Could one identical twin be taller than the other? Why or why not?

Yes depending on what one twin eats how her environment is how she takes care of his/her body

No. Twins are identical and cannot vary in height, eye color, or appearance.

What does a heritability ratio of 1.0 mean?

If genes are totally responsible for all phenotypical differences among individuals, heritability is 1.0.

Genes are not responsible for phenotype.

Hunntington's has a heritabile index of 1.0. What does that mean?

Even if one parent has it, you will inherit it

What that means is that if someone inherits the gene for Huntington’s disease, it is inevitable that he/she will acquire the disease

If you get the gene you will get the disease.

What is genetic drift?

Change in a populations genes from one generation to the next because of chance of accident

Migrated out of DNA

What is Reciprocal Altruism?
