# Statistics maths project Age 14 to 18 This article discusses how a survey company carries out its surveys and some of the issues involved. I also left out 3 sets of figures, for year 7 girls, Age 14 to 18 Challenge Level: A geographical survey: answer the tiny questionnaire and then analyse all the collected responses More generally, data about a random process is obtained from its observed behavior during a finite period of time.

On 1 of the questions asking the persons IQ, the person left it empty.

## Definition of statistics in math

But this could be largely inaccurate because one cluster may look the same but in fact be wildly different form the others. I will get 20 boys and 20 girls from Year 7, and 20 boys and 20 girls from Year 8. You select one cluster or more from random random sampling and use all its people as your sample. Prehaps they didn't know their IQ. Main article: Nonparametric statistics Nonparametric statistics are values calculated from data in a way that is not based on parameterized families of probability distributions. Age 16 to 18 Challenge Level: When is an experiment described by the binomial distribution? Why do we need both the condition about independence and the one about constant probability?

Age 16 to 18 Challenge Level: When is an experiment described by the binomial distribution? This will make my data more stratified and lessen anomalies because the data for girls may follow a different pattern, to the data for boys. It includes many techniques for modeling and analyzing several variables, when the focus is on the relationship between a dependent variable and one or more independent variables. In regression analysis, it is also of interest to characterize the variation of the dependent variable around the regression function which can be described by a probability distribution.

Why do we need both the condition about independence and the one about constant probability? How does it help to catch and mark 40 fish? Main article: Probability distribution A probability distribution is a function that assigns a probability to each measurable subset of the possible outcomes of a random experiment , survey , or procedure of statistical inference. I would've liked perhaps a bigger sample size which wasn't possible because I didn't have enough time to send and collect that many questionnaires but overall, I am happy with the results I have obtained. But if the results show a positive correlation or negative , then I will also plot lines of best fit and find the equations of them it as this will be beneficial in predicting the supposed weight of certain heights of people and vice versa. Age 14 to 16 Challenge Level: I need a figure for the fish population in a lake. Age 14 to 18 Challenge Level: Can you work out which spinners were used to generate the frequency charts? Age 16 to 18 Challenge Level: How many trials should we do in order to accept or reject our null hypothesis? Do you? Age 14 to 18 This article explores the process of making and testing hypotheses. Statistical theorists study and improve statistical procedures with mathematics, and statistical research often raises mathematical questions. I will get some data off government web sites. This simple problem may challenge your ideas

Also how much is 'Lots'? Try the activities to delve into the concepts of hypothesis testing, sampling, and distributions, and explore some of the fascinating and complex issues surrounding the interpretation and representation of data.
