Do the Teacher's (at GHHS) years of experience match the school's claim?
Transcript of Do the Teacher's (at GHHS) years of experience match the school's claim?
Another possible weakness is part-time teaching. If a teacher who gave an answer of five years of experience actually spent 4 of those years teaching part-time, they would truly belong in the 0-3 years teaching experience category. Extrapolating our results During the course of this study, we have decided that this data cannot be used to infer data about other schools in North Carolina. This is due to the fact that Green Hope High School is recognized as one of the best public schools in the state, and it is located in a very prosperous area of the state (relative to other schools). Extensions In addition, we think that a linear regression test should be performed on teacher’s number of years of experience and the average student’s final exam score. This would give us more insight into using years of experience as a measure of how effective a teacher is. In our study, we wanted to determine whether or not the percent of teachers with a certain number of years of experience matched what the school has posted online at NC School Report Cards. We randomly selected thirty teachers from the 119 that are teaching at Green Hope High School and found out how many years they had been teaching for. After compiling the data it was determined that percentages we got from our sample of teachers was very close to the percentages posted online. Therefore, we can conclude that the percentages posted on NC School Report Cards are valid. From our data we can also conclude that Green Hope has a majority of highly experienced teachers which may stem from the fact that it is located in a fairly prosperous area. Ho: The teachers' years of experience match the school's claim.
Ha: The teachers' years of experience does not match the school's claim. Randomization: We used a SRS to collect our data.
Large sample size: We made sure that all expected counts are at least five.
Independence: We had to check if the popluation was above ten times the sample size. The population is not above ten times the sample size. Proceed with caution. Chi-Squared Goodness of Fit Test d.f.= categories -1 d.f. = 2 p-value = .98 p-value < alpha
Therefore, we fail to reject the null hypothesis. .98 ≮ .05 We do not have sufficient evidence to conclude that the teachers' years of experience do not match the school's claim.
