1.6.A1 The correlation between smoking and incidence of cancers.
- Explain the use of correlations to determine the relationship between two variables (inclusive of positive and negative correlations).
- Explain why the existence of a correlation does not necessitate a causal relationship between two variables.
- Calculate a correlation coefficient using Pearson's R.
- Determine if a correlation coefficient value is significant.
- Define significant as related to the relationship between two variables.
- Use epidemiological case study information to outline the relationships between smoking and cancer.
1.6.S1 Identification of phases of mitosis in cells viewed with a microscope or in a micrograph.
- Determine the phase of mitosis of a cell viewed in a micrograph or with a microscope.
1.6.S2 Determination of a mitotic index from a micrograph
- State the formula for calculation of a mitotic index.
- Calculate the mitotic index of a tissue as seen in a micrograph.
- Outline the use of mitotic index calculations in diagnosis and treatment of cancer.
1.6.NOS Serendipity and scientific discoveries- the discoveries of cyclins was accidental.
- Outline the discovery of cyclins including the role of serendipity.
