Description
Παίξτε με το Plinko και αποκτήστε γνώσεις στατιστικής. Ρίξτε μπάλες από την κορυφή ενός τριγωνικού πλέγματος που αποτελείται από πασσάλους και παρακολουθήστε τις τυχαίες πορείες που διαγράφουν οι μπάλες καθώς περνούν ανάμεσα από αυτούς. Παρακολουθήστε τη δημιουργία του ιστογράμματος των τελικών θέσεων και προσεγγίστε τη διωνυμική κατανομή. Εμπνευσμένο από το Εικονικό Εργαστήριο για τις Πιθανότητες και τη Στατιστική του Πανεπιστημίου της Alabama στο Huntsville (www.math.uah.edu/stat)

6.SP.A.2
Understand that a set of data collected to answer a statistical question has a distribution which can be described by its center, spread, and overall shape.
6.SP.B.4
Display numerical data in plots on a number line, including dot plots, histograms, and box plots.
6.SP.B.5c
Giving quantitative measures of center (median and/or mean) and variability (interquartile range and/or mean absolute deviation), as well as describing any overall pattern and any striking deviations from the overall pattern with reference to the context in which the data were gathered.
7.SP.C.5
Understand that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring. Larger numbers indicate greater likelihood. A probability near 0 indicates an unlikely event, a probability around 1/2 indicates an event that is neither unlikely nor likely, and a probability near 1 indicates a likely event.
7.SP.C.6
Approximate the probability of a chance event by collecting data on the chance process that produces it and observing its long-run relative frequency, and predict the approximate relative frequency given the probability. For example, when rolling a number cube 600 times, predict that a 3 or 6 would be rolled roughly 200 times, but probably not exactly 200 times.
HSS-IC.A.2
Decide if a specified model is consistent with results from a given data-generating process, e.g., using simulation. For example, a model says a spinning coin falls heads up with probability 0.5. Would a result of 5 tails in a row cause you to question the model?
HSS-ID.A.1
Represent data with plots on the real number line (dot plots, histograms, and box plots).
HSS-ID.A.2
Use statistics appropriate to the shape of the data distribution to compare center (median, mean) and spread (interquartile range, standard deviation) of two or more different data sets.
