Question

Which variable is kept constant?
(ii) Which reading is anomalous?
(iii) Suggest one improvement in this experiment.
​

Answer 1

Answer:

1. Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.

2. An anomalous result is a result that doesn't fit in with the pattern of the other results. It is an anomaly. Taking many repeat measurements or having a large sample size to analyse will improve accuracy.

3. There are a number of ways of improving the validity of an experiment, including controlling more variables, improving measurement technique, increasing randomization to reduce sample bias, blinding the experiment, and adding control or placebo groups. Measurement technique can also be improved.
