BHS Report Card
1. Is BHS a SRS?
2. Describe whether or not BHS is a representative sample of the population.
3. Do you want to be < or > the mean?
4. Is the mean the end all be all summary statistic?
5. What other statistics would you like to know?
6. Consider how the mean could be expressed.

ReplyDelete1. We're not a SRS because although we are a small sample out of a larger population(Mass schools) we are not chosen randomly. But what is the population of interest? If it is the district we are not a sample because we're the population(the only high school).
2. Somewhat because we're close to average.
3. It depends on what category. Overall we would want to be above the mean on our performance but in the category of suspension/discipline or averages we want to be below the average.
4. No because you need to consider all aspects of what makes the average.
5. We would like to know the ACT scores, what makes a teacher highly "qualified" and what are considered core classes.
6. It could be presented as a range rather than a single number.

ReplyDelete1. This is not a simple random sample, because the population is the entire state and Beverly is not necessarily representative of the state.
2. No because Beverly has its own specific demographics that are not the same as any other area.
3. It depends on the statistic. Some things its better to be below, like detention or suspension rate, other things it is better to be above, like SAT scores or AP success rate.
4. No because there is a lot of factors behind the mean that are not shown in that one number.
5. We would like to know the statistics about ACT scores, the different statistics for SAT scores between people who took SAT prep classes and those who didn't, and the time period from which the scores were taken.
6. The mean could be expressed as a consolidated number, or it could be divided by time period, grade, age, income, or other groupings.

ReplyDelete1. No, the sample of high schools in a particular district is not a random one.
2. It is representative of the population of the district, for BHS is the only school in said district. For the state however, Beverly is a moderately representative sample. We tend to fall close to other school's averages.
3. Greater than the mean for average test score statistics, lower than the mean for statistics like suspension rates.
4. No, it is essential that you consider all components of a data collection, rather than just the mean. Typically it depends on the statistic that it's describing.
5. Our group would like to know the amount of AP classes offered at other schools, because depending on the variety in the options, it is more or less likely for a lot of kids to take AP classes.
6. The mean of the SAT scores could be expressed in different groups, such as "Juniors taking SATs" versus "Seniors taking SATs" or "People who have taken the SATs more than once" vs "People who taken the SATs once."

ReplyDeleteOne interesting statistic we found is that BHS is in the 37th percentile for school performance. We would like to know the details of what's behind this statistic. Something else that we would like to know about is our school's ACT scores compared to other schools.
1. No, BHS is not an SRS.
2. Yes, because the averages in our school are similar to the averages of other schools in our state.
3. We want to be greater than the mean in some cases, yet in others it would be better to be below the mean. For example; absences and suspensions.
4. This depends on the statistics that it's describing. It's not resistant to outliers which could make it less reliable. Sometimes instead you may want to know the median or standard deviation.
5. We would like to know our school's ACT scores compared to other schools in the state. We would also like to know how our state's school report cards compare to other states.
6. The mean could be expressed as the median, standard deviation, variance, or mode. It is an average.
2. There are some statistics where we over or under represent the population, but for the most part, we represent the population well.

ReplyDelete1. BHS is not a SRS if the population is the district because BHS is the only high school. If the population is the State, than BHS is a SRS.
2. BHS is not a representative sample of the population if the population is the district. The district is made up of all elementary, middle, and high school students. BHS only has older students obviously, so it is not representative because there are no younger children. If the population is all of the high schools in the state, BHS could be a representative sample depending on what statistics you look at.
3. You want to be above the mean in the majority of the categories, especially the grades and scores. You want to be below the mean in stats such as suspensions and absences.
4. The mean gives the average, but there are many other statistics to look at like IQR, median, range, standard deviations, etc.
5. We would like to know the average ACT scores of students at our school compared to the state.
6. The mean could be expressed by the mean of our school, the mean of our district, and the mean of our school.

1. No, BHS is not a simple random sample because it is not random and it is a single school. It is specifically given its own report.
2. BHS is a pretty good representative of a sample for Massachusetts, but it wouldn't be too great as a lone school for the country or another state.
3. We want to be greater than the mean because that would mean that BHS is better than the calculated average for certain statistics. For other ones like suspensions and absences we would want to be below the average.
4. No, the mean should be studied as an important statistic, but all of the other ones should definitely be considered as well.
5. We would like to know how Massachusetts schools and how BHS compare to those in other states or even to all schools on a national level. Also, we would like to know how many graduating students pursue higher education.
6. The mean can be expressed as a range instead of a single number. Sometimes the median is used as the mean or the average.

ReplyDelete1. No, because we are the only school in our district.
2. No, because not every high school is the same. For example, we have technology that other high schools do not have.
3. Greater than the mean for academics and test scores. Less than the mean for disciplinary things.
4. It depends because the mean might be the best statistic but then it might not. The median might be a better example.
5. What percentile are we compared to the rest of the country?
6. For comparisons, the mean could be grouped into different areas of mass. An example would be schools from the North Shore.
